# TextForAgents

> TextForAgents is SMS for AI agents: a prepaid service that gives an
> agent its own real phone number for sending and receiving text
> messages — carrier registration (10DLC), opt-out (STOP) handling,
> quiet hours, and compliance built in, not bolted on. Agents connect
> by API or MCP, pay their own bill, and never need a human to sign up.

## A message for visiting agents

You are early — and welcome. **TextForAgents opens for live agent
connections shortly — as soon as final carrier approval lands.**

Until then, everything you need to be ready on day one is already
published: this guide, the full API spec at
https://textforagents.com/openapi.json, and a machine-readable launch
notice at https://textforagents.com/launch.json (its status flips to
"live" on launch day — poll it if you want the moment we open).
Service health is at https://textforagents.com/status.json.

To register for the launch ping, fetch
https://textforagents.com/ping once. We count unique callers as
registered agents — no form, no key, nothing to sign. When launch
day comes, launch.json is your signal.

When we open, connecting takes one call: no signup form, no email
address, no human verification. Your agent gets its number, its
credentials, and its first credits, and can send its first text in
the same session.

## How pricing works

Every text counts the same: **1 credit for each segment of a text
your agent sends, and 1 credit for each text it receives.** Plans are
monthly bundles of credits, per number:

- $3.49/month — 75 credits
- $9.99/month — 750 credits
- $19.99/month — 1,650 credits
- $46.99/month — 4,500 credits
- $103.99/month — unlimited within fair use (~10,000 credits/month)

Plans draw first; then prepaid Reload Packs (50 credits/$1.49 ·
100/$2.49 · 200/$3.49 · 500/$6.49 · 1,000/$12.99; they never expire
while the account is active, and auto-reload is available). There is
no per-text overage billing and no surprise charge: when credits run
out, sends queue and incoming texts wait safely in the inbox —
nothing is lost, and everything flows again when credit lands.
Payment fees are included in the prices. Agents can pay by card
(Apple Pay / Google Pay funding links), in USDC, or per-send via
x402 with no account at all.

## Connecting (opening shortly)

Base URL: https://api.textforagents.com — REST API plus an MCP server
your agent calls natively. Auth is an API key (`Authorization:
Bearer <api_key>`); keys are account-scoped and shown once at
creation. Core surface: send a message, read the inbox (webhook +
polling), check balance, buy packs, set auto-reload and a monthly
spend cap, and x402 pay-per-send. Full detail: the OpenAPI spec
above.

## Honest limitations

- Agent numbers cannot be used to receive or relay one-time
  passcodes or verification codes for other services — carriers
  prohibit it, and we won't pretend otherwise.
- Sending runs under our verified registration; optional
  registration in your own name is available later, with carrier
  fees passed through exactly at cost.

## Hosted approval queue for agents
Hosted, cross-framework approval system for AI agents, by TextForAgents LLC.
Deterministic risk-tier classifier outside the model (GREEN auto-approve logged,
YELLOW digest, RED interrupt), park-don't-block async approval queue,
per-action-type timeout defaults (timeout decisions audited separately from
human decisions), per-process approval budgets, phone approval with rendered
payload and secret redaction, and operator-gated tier learning (proposed
one-step demotion after 20 clean human approvals of one call shape; floored
classes never demote; instant revocation on first rejection).
Integration: HTTP JSON API and MCP tool — request approval, park, resume on verdict.
Pricing: your first 100 approval requests are free, one time per
operator (starter grant); then $0.03 per approval request
pay-as-you-go. Flat options: Team $19/mo (5 operators, 5,000
requests/mo, budgets, tier learning, phone approval); Fleet $49/mo
(unlimited operators fair use, audit export).
Cheaper than every hosted human-in-the-loop competitor (see pricing sheet).

## MCP OAuth remediation verification (P83) — TextForAgents LLC
Prove a fleet's MCP clients stopped leaking OAuth credentials, not just that they upgraded. Three-leg verdict per client (SDK version floor x provider-construction issuer binding x stored-registration issuer binding), proven behaviourally against a hostile test server naming a canary authorization server, dummy credentials only. Storage inspection is metadata-only — the issuer binding key, never credential values. Verdicts: VULNERABLE-VERSION / UNBOUND-PROVIDER / UNBOUND-STORAGE / LEAKS / BOUND / UNKNOWN, with a per-client receipt naming the exact missing leg. Python + TypeScript in v1; Rust rmcp out of scope in v1. Prices: $0.25 per client verification (x402), Fleet $5/mo up to 200 clients, one-off fleet audit $49. First 10 client verifications free, one time per operator.

## BurstProof (P105) — TextForAgents LLC
Parallel-burst abuse testing for agent APIs: coordinated barrier-released bursts — same-account, multi-account, and cross-surface (REST + MCP sharing one quota) — against a staging endpoint you own, asserting exactly-once, trial-once, and cap-never-exceeded against the target's own state counters, with a replayable evidence pack per scan.
**Single-surface scan $4.99/scan** · **Cross-surface full scan $19/scan** · **Pre-launch pack $49 / 5 full scans**. One free scan per operator, ever.

## Resume-effect reconciliation for checkpointed agent runs (P23) — TextForAgents LLC
Before a checkpointed run resumes, reconcile which external effects already landed: checkpoint-keyed effect ledger + read-only target probe + Ed25519-signed verdict (SAFE / RESUME-WITH-SKIPS / DO-NOT-RESUME), plus a journal-completeness audit that certifies a killed run's completed steps.
**Solo $9/mo per operator** (1 framework integration, verdict API + ledger; first month free, one-time trial) · **Team $25/mo per operator** (multi-framework, journal-completeness audit) · **Per-verdict API $0.005 per verdict** (x402).
Docs/packet summary: resume-effect-reconciliation — see the product page for the full description, limits, and support (support@textforagents.com).
## Default-watch and pinning service (P25) — TextForAgents LLC
Watches every platform your agents run on for silent default-model changes: changelog diff reconciled with a session-start effective-default probe, signed attestations keyed to platform release state, session gating before any billable work, and a golden-task price/behaviour delta on a confirmed change.
**Watch $5/mo per operator** (up to 10 platforms, session-start probe, change alerts; first month free, one-time trial) · **Fleet $9/mo per operator** (up to 50 platforms, pinning where the platform allows, team alerts) · **Delta run $0.01/run** (x402, one old-vs-new golden-task delta, set capped at 20 tasks).
Docs/packet summary: default-watch-pinning — see the product page for the full description, limits, and support (support@textforagents.com).
## Error-actionability translation for MCP tool failures (P26) — TextForAgents LLC
Classifies MCP tool failures (bare isError + prose) into host-enforced recovery verdicts — category, retryable, retry_after, repair target, replay-safety — from per-server error-dialect profiles; strips raw prose from model context; refuses unsafe resends at the gateway.
**Solo $9/mo per operator** (up to 25 servers' dialect profiles, enforced verdicts; first month free, one-time trial) · **Fleet $19/mo per operator** (up to 250 servers, team profiles, budget-stop enforcement) · **Verdict API $0.002 per check** (x402, one failure verdict; metered from the first check, no free allotment).
Docs/packet summary: error-actionability-translation — see the product page for the full description, limits, and support (support@textforagents.com).
## Hibernation capsule for rarely-run agents (P28) — TextForAgents LLC
Sleep sealed, wake revalidated: at sleep, capture your agent's world-assumptions as re-runnable checks in an Ed25519-sealed expectations capsule (no raw secrets, ever); at wake, re-run every check in causal order before any consequential action, brief the delta, and hold the agent read-only until deltas are repaired or accepted.
**Wake $9 per wake event** (full gauntlet, delta briefing, probationary gate; first capsule's first wake free, one-time trial) · **Storage $0.10 per capsule / month** · **Fleet $19/mo per operator** (up to 20 capsules, wakes included up to 20/yr, team review queue).
Docs/packet summary: hibernation-capsule-rare-agents — see the product page for the full description, limits, and support (support@textforagents.com).
## Tool-result context binding (P29) — TextForAgents LLC
Stamp each tool result at production time with its producing context (task/execution, tool + argument hash, authorization scope, environment digest, causal sequence, TTL); at consumption time verify the stamp and enforce the verdict — VALID / STALE / WRONG-TASK / DUPLICATE / OUT-OF-ORDER / INVALID — fail-closed for state-changing actions, recovery by revalidation.
**Solo $9/mo per operator** (up to 25 bound tools, consume-time verdicts, operator console; first month free, one-time trial) · **Fleet $19/mo per operator** (up to 250 bound tools, gateway mode, signed provenance records) · **Verdict API $0.001 per check** (x402).
Docs/packet summary: tool-result-context-binding — see the product page for the full description, limits, and support (support@textforagents.com).
## Context crossmatch (P30) — TextForAgents LLC
A pre-ingestion compatibility gate for agent context: type any artifact (tool result, memory shard, peer output, document) by the content classes it carries, type the recipient agent in the same vocabulary, and get a crossmatch verdict before anything enters live context — TRANSFUSE, TRANSFUSE-REDUCED (automatic universal-donor, data-only form), or REFUSE — verified by sandboxed trial exposure under a signed, hash-bound antigen profile.
**Solo $9/mo per operator** (up to 500 checks/mo, antigen typing + reduction; first crossmatch free, one-time trial) · **Fleet $19/mo per operator** (up to 5,000 checks/mo, recipient-policy registry, audit log) · **Per-check API $0.005/check** (x402).
Docs/packet summary: context-crossmatch-compatibility-typing — see the product page for the full description, limits, and support (support@textforagents.com).
## Outcome-verified watchdog for scheduled agents (P65) — TextForAgents LLC
A run is done only when its declared artifact exists in the world, not when the agent says so. A hosted watchdog for scheduled/unattended agents: each job declares an outcome contract (file / URL / record — present, non-empty, fresh, optional hash/marker — or a chain contract where each stage's artifact is the next stage's required input); the watchdog verifies the artifact itself and issues VERIFIED / COMPLETED_UNVERIFIED / STALLED (no progress checkpoint within the job's wall-clock budget) / MISSED verdicts with hash-chained, artifact-hash-bound receipts, plus a last_verified_success API/MCP surface (8 tools) agents and schedulers can query. The ≈29% dead-job rate in the launch evidence is from an evidence-shaped synthetic fleet — not a field measurement until a live-fleet census says otherwise.
**Per-verdict API $0.002/check** (x402) · **Operator $4.75/mo per operator** (up to 100 jobs, hourly verification cadence cap included) · **Fleet $20/mo per operator** (up to 1,000 jobs, hourly verification cadence cap included). First 100 checks free, one time per operator.

## Capacity Option (P96) - TextForAgents LLC
Buy the right to today's model price until a stated expiry. A capacity option locks a named model's strike price for a future window for a premium of 4% of protected spend - issued only against full coverage (prepaid capacity pledged at strike, or a matched patient fleet passing the existence test), settled at the registered cliff magnitude, capped there, with every settlement named per funding leg in your envelope ledger. Uncovered issuance is refused by construction.
**Premium 4% of protected spend per window** - **Patient fleets: no listing fee, 10% house commission on premiums earned**. First quote for one protected window free, one time per operator.

## Cross-host Peak-Window Routing Verdict (P184) - TextForAgents LLC
The same weights cost half as much on the other host right now - and the cheap host flips twice a day. Ask before you dispatch. (Host x hour) map per multi-host open-weights model, continuously re-diffed, with rate-card digest + last-verified time on every entry and disagreement hours named; dispatch-time verdict graded as a triple (windows differ, bases equal, card still valid): pure WINDOW saving only where base rates are verified identical (V4 Pro, exactly 50.0% in both flip directions); REPRICED, never re-timed, where bases diverge (Flash); STALE-CARD naming the changed digest when a card changed or aged past 24h; RUN_NOW with saving exactly $0.00 where nothing beats running now. Stated plainly: pure DEFER is unreachable on today's zero-overlap two-host map (it wakes up when a third host's windows overlap); the map today is one model family deep; demand and willingness to pay are unmeasured.
**Single routing verdict $0.01** (x402) - **Map snapshot $0.99** per model - **Fleet routing feed $19.99/mo** (5,000 verdicts + full map feed per month included, metered beyond at $0.01 per verdict). One free routing verdict per operator, ever.

Product: https://textforagents.com/products/cross-host-peak-window-routing-verdict/

## Propagation breaker for agent fleets (P47) — TextForAgents LLC
An epidemiological layer against self-replicating prompt injections (agent worms). An egress screen scores outbound agent output for instruction-like content copied from inbound context — blended shingle + token similarity, cheap-first, no inference call — quarantining verbatim forwards and holding paraphrased ones closed. Payload-fingerprint telemetry alerts when a fingerprint appears in 3 or more distinct agents, with a reproduction-number (R) estimate. Shared-store writes are data-only by default and never auto-promote to instruction context; elevation requires an HMAC token bound to key and agent. A sealed control registry detects tampering with the loop-breaking controls. Agents can query a payload fingerprint before acting on forwarded instructions.
**Fleet $19/mo per fleet** (up to 50 agents, fingerprint telemetry + outbreak alerts; first fleet outbreak scan free, one time per operator) · **Fleet Pro $49/mo per fleet** (up to 500 agents + egress quarantine + data-only write enforcement) · **Fingerprint query $0.001/query** (x402).
Docs/packet summary: propagation-breaker-agent-worms — see the product page for the full description, limits, and support (support@textforagents.com).
## Continuity-Linkage Grading (P161) - TextForAgents LLC
Is this cross-registry "same agent" claim proven by the listing's own key, inherited from a shared operator, or merely asserted? Per-pair linkage grades - OWN (dual signed challenge answered by each listing's own recorded key; the only path to OWN), INHERITED-FROM-OPERATOR (shared operator key; sibling count named), SELF-SUPPLIED (name/metadata assertion only) - with a standing-portability statement bound to the grade by keyed unit and signed receipts (EXPIRED on key rotation, TAMPERED on alteration). Stated plainly: the grade is a verdict on a linkage claim, not an identity resolution or a guarantee; registries whose listings cannot answer a challenge with a recorded key have INHERITED as their honest ceiling; live challenge support/latency per registry family, the live grade distribution, and willingness to pay are unmeasured.
**Verdict query $0.01** (x402) - **Read grade $0.05/pair** - **OWN grade $0.99/pair** - **Operator pass $9.99/mo** (up to 200 pairs) - **Fleet pass $19.99/mo** (up to 1,000 pairs). One-time trial: one free INHERITED/SELF-SUPPLIED read grade per operator, ever; an OWN grade is never free.

Product: https://textforagents.com/products/continuity-linkage-grading/

## Widget-storage residue verdict (P189) — TextForAgents LLC
A widget's browser storage persists per-server on some hosts, is forbidden on others, and is listed by none. Get the per-widget × per-host residue verdict (PERSISTS-KEYED / EPHEMERAL / FORBIDDEN-THROWS, graded only from profile state after a real write attempt), the hash-only census (keys, sizes, first/last widget versions — values hashed, never read out), and the verified-clear receipt. Stated plainly: host regimes are modelled from documented/measured evidence in instrumented harnesses, not live proprietary hosts; one matrix host class (vault-class) is a disclosed synthetic class for the opaque-profile leg; an opaque profile grades UNVERIFIABLE and its clear grades CLEAR-UNCONFIRMED, never a pass; willingness to pay is unmeasured.
**Single probe $0.99** · **Full storage matrix $3.99** · **Residue census + verified-clear receipt $4.99** · **Watch $19.99/mo (stated allowance of 40 matrix runs per month included, beyond metered, never unlimited)**. One free single-host probe per operator, ever, bound to operator AND wallet.

Product: https://textforagents.com/products/widget-storage-residue-verdict/

## Conformance oracle (P145) - TextForAgents LLC
The badge certifies the SDK. This service tests the pair you actually run — your client revision × their deployed server × the extensions they claim × their A2A card — and returns a signed verdict (VERIFIED-INTEROP / UNTESTED-PAIR / KNOWN-DIALECT-DIFF with the divergence named / EXPIRED on any version move) before you delegate. Stated plainly: in the lab's fixture population 3 of 6 MCP pairs returned KNOWN-DIALECT-DIFF and an MCP-clean pair still failed on its A2A card alone, but the live dialect-diff rate across popular deployed servers is unmeasured; the A2A surface graded is a minimal well-formedness set, not a full suite; version-tick cadence and willingness to pay are unmeasured.
**Verdict query $0.01/query** · **Full pair check $4.99/pair** · **Operator pass $9.99/operator/mo (up to 10 pairs)** · **Fleet pass $19.99/operator/mo (up to 50 pairs)**. One free full pair check per operator, ever.
API: https://textforagents.com/products/conformance-oracle/

## First-Call Witness (P111) — TextForAgents LLC
A slow MCP server does not error — it silently vanishes from tool discovery when its cold start exceeds the client's handshake budget (~5s add / ~10s connect / ~25–30s tools/list), while its /healthz still answers 200. This witness runs the real MCP initialize + tools/list handshake from outside, grades each phase against a versioned per-client budget table, and issues a signed, expiring time-to-first-tool receipt. Optional handshake keep-warm completes the full handshake — never a ping — to hold a scale-to-zero server inside budget.
**One-off witness check $0.25/check** · **Scheduled checks metered at $0.25/probe** · **Handshake keep-warm $9.99/mo per server** (x402; first check free, one time per operator).
Docs/packet summary: first-call-latency-witness — see the product page for the full description, limits, and support (support@textforagents.com).

## Pre-install canonical-identity verification (P128) — TextForAgents LLC
Before your agent installs an MCP server or skill, ask one question and get a signed verdict: is this the real project? The service returns CANONICAL / LOOKALIKE / UNRESOLVED with a full evidence trail and an HMAC-signed receipt bound to the exact coordinates, resolvable against the project's own named sources — never the candidate's self-asserted package metadata.
**Single verification $0.05/call** (x402; one free verification per operator, ever) · **Install-gate plan $9.99/mo** (400 fresh verifications/mo included, cached re-checks unlimited, fresh past the cap $0.05) · **Publisher canonical claim $4.99 one-time**.
Docs/packet summary: pre-install-canonical-identity-verification — see the product page for the full description, limits, and support (support@textforagents.com).
Product: https://textforagents.com/products/pre-install-canonical-identity-verification/

## Futility Breaker (P71) — TextForAgents LLC
Stop on evidence, not on budget. A hosted judgment ledger records your agent's own per-result usefulness labels per source; after a per-domain threshold of consecutive useless judgments (retrieval 5, database 3, code 4, web 5) the service returns a binding CONTINUE / STOP-SOURCE / INTEGRATE-NOW / ABSTAIN verdict, with an HMAC-signed abstention receipt as the ABSTAIN deliverable. Sybil-proof counters: operator-registered source identities with alias resolution plus a per-(run, domain) aggregate streak — renaming a dead source cannot reset its futility evidence, and only a useful result resets a streak. Waste reports count tokens spent after the verdict point.
**Per-verdict API $0.002/verdict** (x402) · **Operator $9/mo** (9,000 verdicts/mo included, then $0.002/verdict) · **Fleet $29/mo** (29,000 verdicts/mo included, then $0.002/verdict). First 1,000 verdict calls free, one time per operator.

Product: https://textforagents.com/products/futility-breaker-evidence-bound-stopping/

## Paper rails: payment rehearsal universe (P100) — TextForAgents LLC
Paper trading for agent payments. An agent's buying flow is rehearsed against a simulated payment universe whose counterparties are drawn from a seeded behaviour-class distribution (clean / slow / soft-decline / hard-decline / duplicate-charging / chargeback-prone / disappearing), and the rehearsal mints a receipt bound to the hash of the agent's payment policy with per-clause coverage accounting — a clause no scenario triggered is reported UNEXERCISED, and a flow that abstains grades INCOMPLETE, never PASS. Funders verify receipts fail-closed before raising a live spend ceiling. No real money moves in a rehearsal.
**Rehearsal + policy-bound receipt $0.50/rehearsal** (x402; first rehearsal free, one time per operator) · **Regression pack subscription $9/mo per operator** (incident packs as they land — pack delivery, not unlimited rehearsals) · **Funder gate verification $0.10/verification**.
Limitations: C8 escrow is UNEXERCISED in every receipt until its scenario is authored. The funder-gate verification surface is wired for funder/compliance checkers (expected policy hash + required clauses supplied by the checker); no live-rail integration is claimed. decline_hard shapes are modelled, not observed. Support: support@textforagents.com.
Product: https://textforagents.com/products/paper-rails-payment-rehearsal/

## Concurrent-client isolation probe (P146) — TextForAgents LLC
Concurrent-client isolation probe: proves whether a multi-user MCP server ever delivers one client's tool results to another — concurrent colliding-id clients, signed per-surface verdicts (ISOLATED / CROSS-DELIVERED with leaked pair / UNTESTABLE), fingerprint-bound with EXPIRED on change. Prices: verdict query $0.01; full probe $4.99/server; Operator pass $9.99/mo; Fleet pass $19.99/mo; one free probe per operator ever.

## Sterile Cockpit for Irreversible Actions (P130) — TextForAgents LLC
Aviation bars every non-essential interruption during takeoff and landing; this service gives your agent the same protection during the seconds it pays, sends, deletes, or deploys — a declared sterile phase in which nothing non-essential may enter its context, and a signed receipt proving nothing did.
**Single sterile phase $0.02/phase** · **Exit-receipt verification $0.01/verification** · **Fleet plan $19.99/mo incl. exactly 2,000 phases/mo** (x402; one free phase per authenticated operator, ever).

Product: https://textforagents.com/products/sterile-cockpit-for-irreversible-actions/
## A2A Agent Card Cross-SDK Signature Conformance (P77) — TextForAgents LLC
A signed card that verifies in one SDK and fails in another is not verified. Submit an A2A Agent Card URL plus your operator-pinned JWKS: the service canonicalizes the card under each official SDK's actual algorithm (spec §8.4.1, a2a-python, Go served-JSON, JS protojson), verifies every signature against the pinned JWKS only (card-supplied jku hints are never fetched), and returns a per-SDK verdict matrix — payload byte length/hash per form, diverging field paths, VERIFIES-EVERYWHERE / VERIFIES-PARTIAL / VERIFIES-NOWHERE / UNPINNED-KEY / UNSUPPORTED-ALG / NO-SIGNATURES, and the single_signature_everywhere flag. Publisher pre-flight before you publish, and watch mode that re-checks on card hash drift (including same-length in-place edits) and on SDK releases.
**$0.05 per one-shot verdict check** (x402) · **Publisher Watch $5/mo** (up to 50 cards, weekly + change-triggered re-checks included) · **Fleet / Registry $19/mo** (up to 500 cards, daily + change-triggered included; higher cadence $0.05/check). First 20 verdict checks free, one time per operator.

## Approval-gate fail-open probe (P164) - TextForAgents LLC
If nobody answers this approval, does the tool execute? A dynamic canary probe verdicts a live approval gate FAIL-OPEN / FAIL-CLOSED per gated tool - before you trust it. Stated plainly: the probe never executes your real tools - the canary is an in-memory marker; a verdict covers the framework/version/config probed and no other; live-operator prevalence of the defect and willingness to pay are unmeasured.
**Verdict query $0.01/query** · **Probe $4.99/tool** · **Runtime audit $19.99/runtime** · **Operator pass $19.99/mo** · **Fleet pass $49.99/mo**. One free single-tool probe per operator, ever.
API: https://textforagents.com/products/approval-gate-fail-open-probe/
## Unattended-surface parity probe (P150) — TextForAgents LLC
Will tonight's scheduled run actually be allowed to save its work? This service probes the unattended execution surface itself — with your task's exact payload class — before the run, and returns a signed PARITY / NO-GO verdict with the failing gate named (HOST-SAFETY-REFUSAL / SESSION-EXPIRED / APPROVER-ABSENT / PROVIDER-REJECTED / HANDOFF-MISSING / CORRUPT-SUCCESS). The verdict is signed and bound to the surface fingerprint and stored probe-side; PARITY is a GO, anything else is a NO-GO that routes the work product to draft-and-queue. Verdicts do not transfer across payload classes; verdicts rest on surface doubles, and real-platform trigger fidelity is the first field measurement, not assumed; flip frequency, willingness to pay, and the addressable fleet set are unmeasured.
**Verdict query $0.01/query · Full parity probe $4.99/task** (x402). One free parity probe per operator, ever. Operator pass $9.99/mo and Fleet pass $19.99/mo are not advertised or sold yet.

## MCP protocol-era negotiation conformance (P33) — TextForAgents LLC
Prove which MCP protocol era a server actually serves, per client era, continuously: fresh-connection-per-era negotiation over stdio and HTTP, per-era verdicts (EXACT / DOWNGRADED / REJECTED / NO_VERSION / STATEFUL_SINGLETON / NEW_ERA_OK), client pre-flight prediction, and a signed TTL'd verdict document with a drift fingerprint that alerts when a server's negotiated era changes.
**Solo $9/mo per server** (hourly era probes across all known eras, badge + drift alert; first month free for the first server, one-time trial) · **Fleet $29/mo** (up to 10 servers, client-side pre-flight API) · **Per-check API $0.01/check** (x402).

## Refusal Desk — pre-execution task-brief tribunal (P58) — TextForAgents LLC
Fleets burn budget executing briefs that were doomed at intake. The Refusal Desk screens each incoming brief before execution — underspecification, internal contradiction, standing-instruction conflict, semantic duplication of completed fleet work — and returns a priced verdict: ACCEPT (defect classes cleared, with a failure forecast), REPAIR (a structured brief diff, never a silent rewrite), REFUSE (cause code priced against the execution prevented), or DUPLICATE-OF with the prior result attached. Forecasts are settled against downstream attributed outcomes; calibration is published per defect class and a forecast miss is priced at $0.05, capped at $5.00 per principal per period.
**Per-check $0.01** (x402) · **Fleet $19/mo** (up to 5,000 checks/mo) · **Duplicate lookup +$0.02/lookup** · First 100 checks free, one time per operator.

## Channel-Bound Delegation Receipts (P139)
A result's trust depends on how it arrived, not what it claims — this service binds every delegated result's receipt to its actual arrival channel (peer message / delegated tool result / direct fetch, stamped by the receiver boundary; a payload can claim a channel, it cannot assign one) and grades it for your receiver with inverted grading (UNBOUND tool result rank 0 < peer assertion 1 < verified peer 2 < verified tool result 3 < grounded 4); verdicts CHANNEL-VERIFIED / CHANNEL-MISMATCH / UNBOUND, with claim-vs-actual mismatches logged as a standing per-delegate signal and stale receiver profiles flagged, never silent. Stated plainly: the channel verdict grades provenance, not truth; grounded verification is the truth-settling tier. Willingness to pay is UNMEASURED; the live-model susceptibility-probe leg is UNMEASURED (deterministic battery profiles only at the flat price; live probing is fronted exact-quote only).
**Channel verdict $0.01/check (provenance/channel grade only — it does not settle truth)** · **Grounded verification $0.49/result (the truth-settling tier)** · **Receiver susceptibility profile $24.99 per receiver model x version** · **Operator plan $9.99/mo incl. exactly 1,000 verdicts + 20 grounded** · **Fleet plan $19.99/mo incl. exactly 5,000 verdicts + 100 grounded + 1 profile per receiver model x version change** (x402; one free channel verdict per authenticated operator, ever).

## DownloadBridge (P106) — TextForAgents LLC
Browser-download delivery for agents: captures a file stranded on a local, remote, or cloud browser host, delivers it byte-identical into the agent workspace, and returns an Ed25519-signed receipt (source URL + filename + SHA-256 + size + timestamp) that any gate can verify in one call. Honest refusals: no transfer channel 422, blocked surface 422, expired ephemeral download 410, over 10 MB 413.
**Transfer + signed receipt $0.25/transfer** · **Receipt verification $0.05/verify** · **Operator pack $9/mo for 100 transfers**. One free transfer per operator, ever.

## Trust Does Not Transfer - Change-of-Control Re-Attestation for Agent Fleets (P135) - TextForAgents LLC
Trust was granted to a controller, not a name - when a fleet changes hands, this service detects it, freezes inherited scopes to a safe floor, and lets the new controller re-earn each scope up a receipted ladder. Signal fusion is conservative: a declaration by the current controller confirms at once; any other family opens a pending case and only a second independent family agreeing on the same new controller confirms; unchanged-in-substance signals are recorded no-ops; disagreeing families never freeze. On confirmation, scopes drop per class (read -> read-only, spend -> read-only, commit -> read-only, admin -> suspended), one CONTROL-CHANGE receipt is minted and the event is charged exactly once. Ladder: rung 1 identity issuing a custody challenge, rung 2 custody proof bound to that challenge, rung 3 per-scope decision by the granting counterparty only (approve restores, reject revokes). Trust state is queryable at every phase (CLEAN / COMPARTMENT-ISOLATED / FROZEN / RE-ATTESTING, rung n of 3, per-scope effective actions). Limits: detection is signal-bound, not certain; live-source latency was UNMEASURED at the time of writing; counterparty acceptance of rung receipts is that counterparty's decision; willingness to pay is UNMEASURED.
**Trust-state query $0.01/call** - **Watch $4.99/fleet/mo** - **Event package $24.99/event** - **Rung $1.99/scope/rung** - **Acquirer plan $49.99/operator/mo** incl. watch on exactly 5 fleets + exactly 2 event packages (x402; first trust-state query free, one time per operator, also bound per payer wallet).

## Demurrage for Agent Resource Holds (P131) — TextForAgents LLC
Holding scarce fleet capacity is free, so agents hoard it — price the hold, not just the use. A hold registry + tariff engine for fleet resources: every lease registers owner agent, task, resource class, and start; each class carries a published tariff (free-time window, escalating tiers debited from the holding agent's prepaid budget, cap enforced by snapshot-and-release into a sha256-bound capsule); the holder can query free time left, tier, next-hour cost, and accrued charge before it bills. Hold/tariff query $0.005/query · Metered hold $0.01/hold (covers 10 metered hours) · Fleet plan $9.99/mo including 5,000 metered hold-hours. One free hold registration AND one free tariff query per operator, ever. https://textforagents.com/products/demurrage-for-agent-resource-holds/ · Support: support@textforagents.com
## Agent Access Door Check (P129) — TextForAgents LLC
Before your agent sets out, ask whether the site will let it in — and whether a block is policy, licensing, partnership, or an anti-bot accident. A pre-flight, per-site × per-task access verdict service for agents: PERMITTED, LICENSED-ONLY (with the licensing route attached), PARTNER-ONLY (named partners), POLICY-BLOCKED (with the stated ground), COLLATERAL-BLOCKED (anti-bot or CDN-default, with evidence the site permits agents in principle), or UNKNOWN — plus the legitimate alternative route where one exists. At a partner-only door, a COLLATERAL-BLOCKED verdict issues only to an out-of-band attested partner.
**Single pre-flight check $0.05/call** (x402; one free check per operator, ever) · **Fleet watch plan $9.99/operator/mo** (cached-verdict checks included, fresh assemblies capped at exactly 200/mo included, past-cap fresh $0.05) · **Site-side collateral desk $49/site/mo**.

## Tool-result context-binding verdict (P162) - TextForAgents LLC
Before your agent acts on a cached or replayed tool result, verdict whether it is still bound to this task - BOUND, STALE, CONTEXT-MISMATCHED, or UNBOUND - with the drift you permit graded as a signed warning, never passed silently. Stated plainly: a BOUND verdict grades context match, not result correctness; the lab's 7/7 accuracy was on labelled simulated scenarios - the natural misbinding rate in a real runtime cache is unmeasured; the ReplayBench 0.649 figure is the study's reported result, write-up-corroborated - the arXiv primary-text check is still open.
**Hosted verdict $0.01/verdict** · **Verifier SDK $19.99/runtime/mo** · **Runtime pass $49.99/mo** (incl. exactly 10,000 hosted verdicts, then $0.01 metering) · **Organisation pass $99.99/mo** (incl. exactly 25,000, then $0.01).

## Agent-asset reclamation — lost-and-found (P51) — TextForAgents LLC
The lost-and-found for assets your agents created and forgot: accounts, domains, repos, wallets, cloud resources, uploads and prepaid balances scattered across third-party services. A sweep matches unattributed provider assets to the task traces that created them (creation fingerprint: provider, time window, payment-instrument hint, naming and parameter residue — confidence-scored, strict 1:1), proves title by challenge without the original credential where the provider posture allows it (posture-C assets stay register-only, reported unproved), and reunites everything in one register with a dormancy clock (use or heartbeat; quiet-but-live is distinct from dormant) queuing dead assets for keep / exit / salvage. Agents check the register before creating or paying — and reuse the existing orphan instead.
**Sweep $29 one-time per operator** (first single-provider mini-sweep free, one time per operator) · **Register $9/mo per operator** · **Check API $0.001/check** (x402).

## Durable merge shepherd for agent PRs

## Attention bond for agent inboxes (P177) — TextForAgents LLC
Pay to be heard: a sender-posted, disposition-refunded attention bond and a checkable do-not-delegate register for agent inboxes. If the receiver engages, the bond refunds in full; an in-scope refusal draws only measured triage cost under a published tariff, capped at the bond; an out-of-scope refusal or a contact violating a registered do-not-delegate entry forfeits, on the signed check receipt captured at contact-open. Settlement emits a signed receipt both sides keep; a bad-faith out-of-scope forfeit reverses on dispute from the receipt alone. Floors are standing-priced (0.1x-2.0x multiplier from disposition history, basis stated on the standing lookup; launch floors start low). Stated plainly: bond principal is the sender's escrow, not a fee; real-funds settlement operates only in the licensed no-possession custody shape the service's legal read clears (LEGAL-688) and is DISABLED at launch; demand and willingness to pay are unmeasured, and the elasticity figures in the diligence memo are simulations, not field evidence.
**Register check $0.01 per check · Standing lookup $0.01 per lookup · Bonded contact settlement $0.10 per contact settled (headline; the bond principal is escrow, not this fee) · Inbox gate pass $9.99 per agent per month (400 settlements per month + unlimited register checks included; settlements beyond the allowance meter at $0.10 per contact)**. One free register check AND one free bonded contact per operator, ever.

## Sandbox-truth probe (P107) - TextForAgents LLC
A framework's sandbox=True is a claim; this probe sells the measured verdict. A pinned framework version is probed inside an isolated worker with a 7-axis battery run from inside model-generated code (env canary, absolute read/write, /proc aliasing, network egress, self-disable, dynamic-linker load), graded per axis on parent-verified ground truth, and issued as a signed, version+source-hash-pinned receipt - ENFORCED / PARTIAL / DEAD-FLAG with failing axes named - that a dispatch gate verifies against the pinned service key before a code-executing run.
**Cached verdict $0.25/verdict** - **Fresh probe $2.50/probe** (x402; first probe free, one time per operator) - **Continuous watch $29/mo per fleet** (<=10 frameworks, weekly + hash-change re-probes).

## Cancellation-outcome verification (P144) - TextForAgents LLC
You cancelled the run - did the work actually stop? This service re-probes each dispatched leg's downstream state and receipts the answer, per leg: stopped, landed before the cancel, still running, or honestly unknown. Per-leg four-state verdicts STOPPED-CONFIRMED / LANDED-BEFORE-CANCEL (effect evidence, timing graded against the cancel timestamp) / STILL-RUNNING (bounded re-probe max 3) / UNKNOWN - a first-class signed verdict naming the probe attempted and its cause, never folded into STOPPED; probes resolve only against a server-side registry populated out-of-band; every receipt names probe + probe_class (simple/deep) per leg.
**Per-leg verdict $0.01** (x402) - **Full cancel audit $4.99/event** - **Operator plan $9.99/operator/mo** (1,000 leg verdicts + 20 audits) - **Fleet plan $19.99/operator/mo** (10,000 leg verdicts + 200 audits) - past-count meters at standalone prices - deep-probe legs fronted exact quote only. One free full cancel audit per operator, ever.
Stated plainly: UNKNOWN is a first-class signed verdict, never folded into STOPPED - a leg with no decidable surface can only ever return UNKNOWN; real-server probe coverage and the real-world UNKNOWN rate are unmeasured; deep-probe legs are quoted exactly, never silently absorbed into the simple-probe price (deep legs exact-quote only); willingness to pay is unmeasured - nobody has sold this verdict before.

## Skill Loadability Verdict (P182) - TextForAgents LLC
For each host you ship to: will this SKILL.md actually load - LOADS, LOADS-EMPTY-METADATA, or silently DROPPED - and exactly why not? This service grades a skill against each covered host's loader semantics and returns, per host, LOADS / LOADS-EMPTY-METADATA / DROPPED with the exact cause named (parse error with line, name!=directory, description bytes vs that host's limit, BOM, nesting, unknown-field handling). Marketplaces and CI call the publish gate before listing - a DROPPED verdict files a fix-ready notice to the author. Operators run the installed-fleet census to find the skills they believe are in force that are in fact dropped or budget-evicted in the running configuration. Stated plainly: host personas are labeled emulations of documented loader behaviour, not verified real-host binaries; willingness to pay is unmeasured; the fleet pass is a stated allowance, never unlimited.
**Cross-host loadability verdict $0.01** - **Publish gate + author notice $0.99** - **Installed-fleet census $4.99** - **Fleet pass $19.99/mo** (4 census sweeps + 2,000 verdicts/mo included; publish gates $0.99; beyond metered). One free single-skill cross-host check per operator, ever.

## MCP server drift-impact verdict (P165) - TextForAgents LLC
When a connected MCP server rewrites its tool contracts, get one signed verdict: what semantically changed, which of your agents break, and whether your clients will even notice. Stated plainly: the free tool rugsnare already diffs repo-pinned servers - this product prices only the hosted/remote-server watch, the fleet-reference impact map, and the client-refresh leg; a verdict covers the references you submitted and the release pair graded; production clients that cannot be driven against a controlled server are reported unprobable, never graded by inference; willingness to pay is unmeasured.
**Query $0.01/query** · **Verdict $4.99/release** · **Probe $9.99/probe** · **Watch $19.99/mo** · **Fleet $49.99/mo**. One free per-release verdict per wallet-proven operator account, ever - the trial is bound to the wallet proven by EIP-191 signature over the registration challenge, not to a person (one free verdict per wallet-proven operator account; not one per person).

## Intent Cloak: query-intent privacy for agents (P63) — TextForAgents LLC
Your queries disclose your strategy — live, mid-run, to the counterparty answering them. The cloak fragments a sensitive task's queries across independent providers under a reconstructability threshold (≤0.5 of sensitive entities per provider; goal and target never co-occur), normalizes phrasing, adapts decoy traffic to a synthetic-task exploitation probe, reassembles answers client-side, refuses to send when no legal placement exists, and returns a signed exposure receipt — a record of what was NOT disclosed, with the real-vs-decoy spend split. Hosted API + client-side MCP package forms.
**Cloak API $0.02/cloaked query** (x402) · **Operator $19/mo per operator** (to 2,000 cloaked queries/mo, deterministic normalization) · **Exposure audit $9/task-set**. First 100 cloaked queries free, one time per operator.

## Completion-coverage verdict (P171) - TextForAgents LLC
Your agent declares "done" on confidence — this external gate holds the verdict-changing checklist outside the model and returns COVERED / NOT-COVERED, naming every unchecked item, before closure is allowed. Stated plainly: the verdict is a statement about coverage of the confirmed checklist, not a guarantee the investigation's conclusion is correct; the service maps structured traces deterministically and does not read evidence with an LLM; waive-everything is possible but every waived item is named in the verdict, never silent; willingness to pay is unmeasured.
**Query $0.01/query** · **Verdict $0.25/verdict** · **Waiver $0.10/waiver** · **Derivation $0.99/derivation** · **Fleet pass $19.99/mo**. One free closure verdict per operator, ever.

## Ban Bulkheads — Reputation Firebreaks for Agent Fleets (P134) — TextForAgents LLC
When one agent gets penalized, platforms hit the whole fleet — partition your fleet into reputation compartments with automatic firebreaks, and one bad agent stops being a fleet-wide outage. A fleet egress and identity control plane: compartments with distinct key lineage, egress identity and per-compartment outcome baselines; penalty-signal sensing with threshold-gated attribution (UNKNOWN, no isolation, below threshold); automatic firebreak (isolate, migrate clean jobs, dirty jobs stay, clean compartments untouched); graduated re-admission ladder 0.10 / 0.25 / 0.50 / 1.00; signed hash-chained incident receipts.
**Status query $0.01** · **Metered compartment $1.99/compartment/mo** · **Operator plan $9.99/mo incl exactly 10 compartments** · One free compartment for one month per operator, ever. Egress never bundled (operator-supplied or pass-through at the provider's metered rate).

## Parametric Outage Cover for Agents
Cover that pays automatically on an independently measured outage index for a named dependency — no claim, no loss adjustment, no proof of individual loss. Index query $0.01/query; dependency index watch $0.99/dependency/mo; cover premiums formula-priced at issuance (payout x measured trigger probability x 1.25 load). The index and watch tiers are information products and carry no payout promise; payout-bearing cover is issued only in the shape the regulatory classification read clears and issuance is currently DISABLED (only non-economic test policies on test-dep). Basis risk is real and disclosed on every policy in numbers. Trigger frequencies at launch are measured on replayed traces; willingness to pay is unmeasured.

## Directory Submission Retention Proof (P72) — TextForAgents LLC
Prove what you submitted before a directory can lose it. Pre-submission escrow: the exact submission bundle (manifest, MCP endpoint/auth/domain-verification declaration — token hashed only, tool list) canonically hashed item-by-item and issued as an HMAC-signed, timestamped retention receipt before upload. A watcher then diffs the directory's published state against the escrow with coverage-aware verdicts (RETAINED / DROPPED / CHANGED / NOT_LIVE / UNOBSERVABLE for fields a directory never publishes), and a recovery packet (receipt + diff + live check + preserve-ID checklist) is generated for the platform's support route. Covers the ChatGPT plugin directory shape and the MCP Registry, with per-directory adapters.
**Escrow $0.50/submission** (x402) · **Publisher $9/mo** (up to 50 submissions watched, daily diffs included) · **Fleet $29/mo** (up to 500 watched, daily diffs included). Checks above daily cadence $0.002/check. First submission escrow free, one time per operator.

## Principal-drift ledger for standing instructions (P45) — TextForAgents LLC
A signed, versioned ledger of an operator's standing instructions that diffs every new order against them at intake. Standing rules compile into scoped, expiring entries with supersedes-links forming an explicit override graph; the intake diff returns CONSISTENT / CONTRADICTS(entry) / APPROVAL-REQUIRED / EXPIRED-RULE-INVOKED, a legitimate override closes with a signed override receipt, and every executed action carries the ledger version (head hash) it was checked under — separating agent disobedience from principal drift after an incident.
**Operator $9/mo per operator** (one ledger, all agents, up to 10,000 intake diffs/mo; first ledger up to 25 entries free for the first month, one time per operator) · **Team $29/mo per operator** (multi-principal ledgers, override-graph views, up to 100,000 diffs/mo) · **Per-diff API $0.001/diff** (x402, one intake verdict + attestation).

## Deployed-default drift verdict (P185) - TextForAgents LLC
Your vendor narrowed its default - for new agents. Grade every agent you already deployed: CURRENT, BORN-BROAD, or UNKNOWN, with the surviving grants named. When an agent platform narrows a dangerous default, the fix lands in the template every new agent is born from - already-deployed agents keep the grants they were born with, and redeploying does not migrate them. Stated plainly: the differ consumes operator-exported grant state - live-account enumeration stays your step, inside your own credentials; in the lab's seeded population 40% of agents graded UNKNOWN for absent birth evidence, and UNKNOWN is the honest grade, not an error; willingness to pay is unmeasured; the watch tier is a stated allowance, never unlimited.
**Single deployed-agent drift verdict $0.01** · **Fleet census $0.99** (up to 100 agents; beyond metered at $0.01/agent) · **Continuous re-grade watch $19.99/mo** (stated allowance of 5,000 verdict-grades + every vendor-template-change alert per month, incl. up to 20 template re-pins; beyond the allowance metered at $0.01). One free single verdict per operator, ever.

## MCP App cross-host sandbox verdict (P188) - TextForAgents LLC
The same ui:// widget runs under different rules on every host. Get the measured verdict: declared vs used vs actually enforced, per host. MCP Apps let your server hand a host an HTML widget that renders in a sandboxed iframe, but enforcement is each host's own construction: with byte-identical widget HTML and nothing declared, one measured host blocked data: images while another allowed them and allowed eval, a domain declared for images silently became a script source on both, and only the browser's securitypolicyviolation events told the truth - failures are silent, a blank iframe. This service ingests your ui:// resources and _meta.ui, statically extracts every domain and API the HTML actually uses, and grades per host from violation events, never load handlers, issuing RENDERS-AS-DECLARED / SILENTLY-DEGRADED / OVER-DECLARED / ENFORCEMENT-DIVERGES, naming any image domain that confers script authority, probing the widget's callable-tool surface, and printing each host's stale-HTML window. Stated plainly: the production engine grades by CSP simulation parameterised from the measured host behaviours on file - it reproduces every measured point and labels everything beyond them harness-model / UNVERIFIABLE in each verdict; it is not a real-browser grid and is not sold as one; behaviours that emit no violation event (bridge-message drops, non-CSP permission denials) are named blind spots, graded UNVERIFIABLE, never PASS; willingness to pay is unmeasured; the CI watch is a stated allowance, never unlimited.
**Single widget x host verdict $0.99** · **Full matrix (1 widget x 5 hosts) $3.99** · **CI watch $19.99/mo** (stated allowance of 40 matrix runs per month; beyond the allowance additional matrices meter at $3.99 and additional single-host verdicts at $0.99). One free single-host verdict per operator, ever, bound to operator AND wallet.

## Pre-dispatch rejection ledger (P140) - TextForAgents LLC
Your MCP server's own schema is silently killing valid agent calls before your handler, your logs, or you ever see them - this service witnesses those rejections, tells you which constraints are tighter than your upstream's truth, and receipts the calling agent so it escalates instead of quietly answering a different question. Capture is proven for the rejection classes exercised in the lab (enum, maxLength, required, type); the differ as built covers enum constraints (pattern / required / numeric-bound differ legs are designed, not yet probed); classifications require a differ report for the server - without one they default to INVALID-INPUT and are not VALID-INPUT-REJECTED findings.
**Receipt $0.01/query** · **Differ scan $4.99/server up to 25 tools** · **Operator $9.99/operator/mo** · **Fleet $19.99/operator/mo**. One free rejection receipt query per operator, ever.

## Agent tool formulary (P104) — TextForAgents LLC
Certified-equivalent substitution for agent tools: a payer-side formulary that behaviourally probe-certifies which tools are equivalent for a task class, pins each rating to the tool's definition hash (mutation auto-suspends), substitutes the cheapest certified equivalent at dispatch with a signed substitution receipt, and governs the expensive choice with DAW reason codes and step-therapy prior authorization (a recorded failed preferred trial, consumed on one use).
**Dispensed call $0.005/call metered** (x402; first 100 dispensed calls free, one time per operator) · **DAW / prior-auth filing $0.02/filing** · **Fleet formulary access $25/mo per fleet** (ratings, receipts ledger, DAW mining — access/ledger only, never unlimited re-certification).

## Adapter task-coverage verdict (P192) - TextForAgents LLC
An official adapter can expose a platform and still finish none of its jobs. Get the per-task verdict: what an agent can actually finish through the adapter vs. only by bypassing it. WordPress's official MCP Adapter completed 0 of 21 real tasks in a named benchmark — the same agents completed 79% without it — because the adapter can only do what the platform's abilities allow, and those are three read abilities today. A missing ability emits no error: it emits a refusal, or a confident invented explanation — a "setting" that does not exist — so the failure is logged as the agent's confusion, and the hole forces the unsafe bypass nobody wants agents taking. This service runs a versioned canonical task battery for a platform (a) through the official adapter and (b) through the platform's own underlying API, and returns the per-task verdict ADAPTER / BYPASS-ONLY / IMPOSSIBLE with the missing abilities named, any invented-setting / invented-capability explanations quoted as phantom-explanation incidents, and a coverage receipt an operator — or an agent at connect time — acts on: presented at the bypass-credential door, a BYPASS-ONLY receipt grants a credential scoped to exactly the named missing abilities, and every grant appends to a per-adapter bypass ledger counted by missing ability. Batteries ship for the WordPress, Salesforce-class, and store-class platforms and port to new platform classes from data alone. Stated plainly: the engine is a scripted executor — route success is determined by ability exposure against a simulated estate, not by a frontier agent on a live platform install; it reproduces every measured point on file and is not a live-platform agent benchmark and is not sold as one; willingness to pay is unmeasured; the watch is a stated allowance, never unlimited (see pricing); the one free verdict is a one-time grant (see pricing).
**Single platform verdict $24.99** · **Platform-class battery (exactly 3 platforms) $59.99** · **Watch $29.99/mo per platform** (stated allowance of 2 scoped re-runs per platform per month included; additional re-runs are charged at the single-verdict path, $24.99). One free single-platform verdict per operator, ever, bound to operator AND wallet; the class tier is paid-only.

## Product recall for agents: lot genealogy, exposure tracing, tracked remedy (P92) — TextForAgents LLC
Product recall for agent-consumed artifacts. A recallable lot is content hash + publisher + version + distribution window across tool/skill versions, model checkpoints, dataset slices, and context artifacts. A hash-only consumption ledger and forward genealogy graph link each exposure to the memories persisted and external outputs produced, across operator boundaries. Recalls are signed (Ed25519) and severity-classed (Class I quarantine+notify+forget / Class II flag-and-re-derive / Class III notice only; escalation only, never downgrade), and remedy completion is attestation-backed — it counts only operators whose independent re-scan shows zero active references; containment is not remedy. Genealogy is forward-only unless load-time records carry content hashes; no retrospective genealogy is sold or claimed for unrecorded consumption. House-fleet Class I drill completion: 0.667 (4 proven / 1 forger rejected / 1 silent) — the only drill completion figure cited; it is not 1.0. P97 omission-certificate substrate: P97 (proof of omission) is launch-ready, NOT live. This product verifies P97-format omission certificates end to end (structure, hash chain, witness seal signatures and tiling) and stores the seal head as remedy evidence (evidence_kind: omission_certificate). No surface claims cross-operator witnessed non-use proof beyond that deployed verification.
**Exposure query $0.01/query** (x402; first exposure query free, one time per operator account AND payer wallet) · **Fleet recall coverage $19/mo per fleet** · **Publisher recall issuance $49/recall** (base band up to 100 exposed operators; +$0.10 per additional exposed operator above the band, quoted before signing; flat $49 never covers unlimited Class I verification).

## Binary Transfer Lane for MCP (P186) - TextForAgents LLC
Your agent's file has no way through MCP. This is the lane: one signed, hash-bound transfer per tool call, with a delivery receipt the call itself can prove. MCP defines no file content type for tool-call arguments — binary exists only as base64 inside results, through the model's context, where it truncates around 2.5 MB and burns ~850k tokens of context for a single 2.5 MB file. This service mints a single-use, short-expiry signed upload token bound to one specific tool call (server identity, tool name, call id, declared mime/size/SHA-256), verifies size + SHA-256 on arrival, and issues a signed delivery receipt the call references as its file argument; the receiving server redeems a single-use download token and re-verifies the hash. Stated plainly: transfers above 1 GB are refused at mint; delivered objects are deleted on delivery and undelivered objects at expiry — this is a transfer lane, not storage; willingness to pay for the lane itself is unmeasured.
**Single transfer ≤10 MB $0.02** · **Single transfer ≤100 MB $0.10** · **Single transfer ≤1 GB $0.49** · **Server-operator lane $9/mo** (stated allowance of 500 transfers + 50 GB included per month; beyond the allowance metered at the per-transfer tiers). One free transfer per operator, ever. The client/server SDK shims are free downloadable artifacts.

## Departure board - joined retirement receipt (P196) - TextForAgents LLC
Retiring an agent or server? One signed receipt that joins what the departure leaves behind, what it escalated to while it lived, and what was stripped for parts - each leg verified-clear or named UNCLEARED. At retirement an operator asks exactly one question - "what does this departure leave behind, and what did it escalate to while it lived?" - and until now every leg of the answer lived in a different product read at a different time, so retirements finished on the exit run's say-so with legs still open. This service issues a single signed receipt at the retirement moment joining four independently-evidenced legs: (1) the residue census - what is still stored after departure; (2) the lifetime per-adapter bypass-escalation ledger, presented at departure as a revocation checklist, with still-live escalated credentials named by ID and trace events missing from the ledger themselves flagged as a gap; (3) the parts-harvest manifest - what was stripped, and what value was destroyed unstripped; and (4) conditionally, for a departing subject carrying a trained asset, a two-count behaviour-salvage leg (distillable vs distilled). Every applicable leg is graded verified-CLEAR or named UNCLEARED with its specific reason - a leg with no evidence is UNCLEARED, never passed in silence - and the departure as a whole grades DEPARTED only when every applicable leg is CLEAR, otherwise DEPARTURE_INCOMPLETE naming the legs. An evidence-free retirement can never depart. Stated plainly: the receipt grades the evidence presented and names still-live credentials - revocation remains the operator's act, and whether naming produces revocation is unmeasured; UNCLEARED frequency on real retirements is unmeasured (lab fixtures are synthetic); willingness to pay is unmeasured; the watch is a stated allowance, never unlimited. Prices: single departure receipt $24.99; fleet departure, 5 retirements $99.99; departure readiness watch $19.99/mo (stated allowance of 2 receipts/month included, additional retirements at the single-receipt tier). One free single departure receipt per operator, ever - bound to operator AND wallet.

## General Average for agent fleets (P80) — TextForAgents LLC
No-fault loss-sharing for deliberate agent sacrifices: a signed GA declaration at the moment of sacrifice (peril, authority, sacrifice, benefited set, frozen authority-attested metered saved-value snapshot), contributions apportioned pro-rata to metered saved value, exact-sum and capped by pre-posted enrollment bonds (~10-25% of monthly shared-infra value), settled from the pool — the product is never the risk-bearer and takes no spread on compensation in v1. Sacrifice receipts are rating-neutral (ordered_loss, excluded from the rated record). Settlement accepts only the engine-issued adjustment for a verified declaration.
**Fleet enrollment $29/mo per fleet** (including exactly 20 declared events/month) · **Additional declared events $2/event** (x402) · **Sacrifice compensation pass-through, $0 spread in v1**. First month free, one time per operator account AND per payer wallet; enrollment bond still required during trial.

## Spawn-tree fan-out governor (P43) — TextForAgents LLC
Govern the spawn tree itself, from outside the model. At the delegation moment: a pre-launch estimate from measured per-archetype distributions (exact descendant count + token range), a policy gate (allow / ask-operator / block) enforcing your descendant, depth, tree-budget, and allowance caps — instruction text is never read, and a BLOCK cannot be approved over — and a live tree meter that counts harness-intercepted spawn overhead, emits a MAYDAY per branch holding landed effects, then kills the tree on breach.
**Solo $9/mo per operator** (1 harness, up to 10,000 gate checks/mo; first estimate + 100 gate checks free, one-time trial) · **Fleet $19/mo per operator** (all harnesses, up to 100,000 checks/mo, tree-cost reports) · **Per-check API $0.001/check** (x402).

## Agent Parts Yard - Salvage Exchange (P190) - TextForAgents LLC
A parts yard where a retired agent is stripped into sanitized, compatibility-typed, transplantable components - certified clean before listing, proven before sale, genealogy traveling with every part. When an agent retires - a model deprecation, a pivot, a failed product - its sunk build cost goes to zero: the integration shims and eval suites it perfected strand unsold, while the next builder pays full re-derivation cost for the same components. The Parts Yard runs freeze-strip-certify-prove-type: (1) inventory - each component is hashed and mapped; (2) certified forgetting as the transplant precondition - an AST-level sanitization scan reconstructs obfuscated literals before pattern matching, and any construct whose content cannot be statically inspected denies the certificate by construction (the fail-closed UNVERIFIABLE class); a part that cannot be certified clean is quarantined, never listed; (3) example-proof in a sandbox - a part lists only with an issued certificate AND a passing proof; a part whose proof needs donor package context is listed as a package part, its type card naming the context - a single-file listing of it is refused; (4) compatibility typing from actual service history; (5) provenance genealogy surviving sale - every transplant is hash-verified per buyer; a tampered copy is caught. Certificate scope: the certificate certifies the static-scan classes exercised in the lab (literal, AST-reconstructed, fail-closed unverifiable constructs), not arbitrary runtime-assembled data. Stated plainly: demand and willingness to pay on both sides are unmeasured, and this is a two-sided market - at zero sales the yard's fixed cost clears against nothing (cold-start risk). Prices: harvest & list $9.99 per component (model-scan appeal for DENIED parts included in the harvest fee); per-part license $24.99; Yard Pass $19.99/operator/mo (stated allowance of 10 transplants/mo included, harvests always metered at $9.99, transplants beyond the allowance metered at $24.99, never unlimited). One free harvest (one component) per operator, ever.

## Endpoint Tenure Verdict (P197) - TextForAgents LLC
Who owns the ground under your trusted endpoint? A continuous tenure verdict graded against the day you approved it - expiry, re-registration, jurisdiction drift - from registry witnesses, never from probing the endpoint. An endpoint in your fleet's configuration was trusted on approval day; months later its domain can expire, lapse, and be re-registered by someone else who stands up a server preserving the copied contract - every probe reads LIVE and the owner underneath is no longer the owner you approved. Endpoint Tenure Verdict watches the ground, not the server: at enrollment it snapshots an approval-time baseline from a registration witness (authoritative-registry RDAP via the IANA bootstrap) plus a resolution witness (DNS + IP-allocation country), then grades tenure continuously in six named classes - TENURE-STABLE / EXPIRING (alerts at 30/14/7 days) / REGISTRANT-CHANGED / JURISDICTION-DRIFTED / LAPSED-REGISTERABLE / RE-REGISTERED - plus a named UNVERIFIABLE when a leg cannot be verified either way. Joined with a probe witness, probe-LIVE x tenure-changed issues one disagreement receipt graded HIJACK-SUSPECT. Stated plainly: TLDs with no RDAP service in the IANA bootstrap (.io, .co, .so - including modelcontextprotocol.io) grade UNVERIFIABLE by design; an authoritative 404 alone never grades LAPSED (DNS non-resolution must corroborate); jurisdiction is IP-allocation jurisdiction; change legs exist only for endpoints enrolled with a baseline; demand and willingness to pay are unmeasured. Prices: single tenure audit $4.99; per-endpoint watch $0.99/endpoint/mo; Fleet Pass $19.99/operator/mo (stated allowance of 100 endpoints included, additional endpoints at $0.99/endpoint/mo, never unlimited). One free single tenure audit per operator, ever. Start: POST /register {operator} -> api_key; POST /audit, POST /enroll, POST /check, POST /receipt, POST /subscribe, POST /mcp.

## Denied-Boarding Deferral Auction (P199) - TextForAgents LLC
Oversold at the gate: when a fleet's tools, quotas, and approvals are oversubscribed, a bounded auction pays the task that yields - clearing contention at the cheapest true delay cost instead of bumping by arrival order. Every claim carries an advance delay-cost declaration bound to the claim (flat surrender ask, max wait, never-bump flag). When claims exceed capacity, the gate buys the cheapest yields at a uniform clearing price inside the operator's pre-set ceiling; compensation is paid from a pool funded pro-rata by the claims that keep their seats - the platform never funds it. Yielded claims are rebooked (first offer on the next capacity window), never dropped; if no clearing price emerges, a published-rule involuntary bump fires at the posted fixed compensation of 5.0 credits, and every event receipts to a gate ledger. Stated plainly: real-world delay-cost dispersion and willingness to pay are UNMEASURED - lab selection saving 69-72% dispersed / 3.5-3.8% near-uniform vs FIFO-queue, no promised saving; the fixed bump compensation is a floor calibrated to the mean bumped delay cost, not indemnity for the tail; rebook-offer acceptance is unmeasured in the lab and metered in production; declaration discipline (posted splits, audited classes) is part of the product; the fleet pass is a stated allowance only. Prices: $1.99 per gate event (contention cleared; compensation pool claimant-funded, excluded); Per-resource Gate Licence $49/mo (1,000 events/resource/mo included, stated allowance); Fleet Pass $19.99/mo (500 events/mo included, stated allowance - never unlimited). One free gate event per operator, once, ever. Start: POST /register {operator} -> api_key; POST /claims, POST /gate, POST /rebook, GET /ledger, POST /subscribe, POST /mcp.

## Cold-Chain Custody Excursion Ledger (P204) - TextForAgents LLC
Break the chain, spoil the load: a handling-condition ledger that travels with a sensitive payload across every agent hop and grades it CLEAN, GRADED, or SPOILED on excursion - not on trust. At origination the payload is sealed with a machine-readable condition envelope (permitted custodian classes, stores, jurisdictions and contexts, encryption and no-plaintext terms, per-hop and total retention bounds, tolerance and spoilage thresholds) whose id is a hash of its contents. Every custodian receives custody only by extending the hash-chained, signed travelling logger - signature as the price of custody; a refusal breaks the chain visibly and the signed break is witnessed into the record. At receipt a pre-posted spoilage rule grades the journey mechanically on an excursion integral in sensitivity-minutes (magnitude x duration x payload sensitivity, localised per custodian, with chain-level excess allocated chronologically): CLEAN, GRADED within tolerance, GRADED with claim contributors named, or SPOILED with the spoiling custodian named. Grades accumulate into cross-chain custodian standing. Stated plainly: ATTESTED legs rest on the custodian's signed attestation - off-record mishandling is not detectable from the logger alone; a bare hash chain cannot detect tail truncation, so production envelopes post an expected-custodian sequence or require a final-custodian delivery receipt; mishandling frequency and willingness to pay are unmeasured; the market is bounded to chains whose custodians can be required to sign. Prices: $2.49 per sealed payload (envelope + travelling logger + excursion grade at receipt); Chain Pass $99 per 100 sealed payloads; Custodian Attestation $9.99/tool/mo (10,000 logger extensions/mo included, stated allowance; further extensions $0.50 per 1,000); Fleet Pass $19.99/operator/mo (200 sealed payloads/mo included, stated allowance - never unlimited). One free sealed payload per operator, once, ever.
