# GridZen > Verification services for developers and AI assistants. Mexico identity and beneficiary-account verification accepts authorized CURP and CLABE and returns verification grades, task status and charges. Current merchant capabilities and the accepted quote define supported inputs, prices and required authorization. Web console, authenticated API and merchant MCP share the same service. The anonymous public MCP provides research and synthetic examples. Product-specific merchant MCP profiles require separate merchant authorization, funding and current availability; installation grants no business approval.

Run gridzen setup --client --project . to preview, then add --apply. Workspace trust is required; Desktop and Cline need manual import. Generated configuration is not client or model acceptance. ## Boundaries Optional account/project activation measurement requires explicit consent, retains associations for 90 days, and supports withdrawal/deletion without loss of service. The first user-confirmed content marker and source category may be linked to server-completed synthetic runs; unknown origins remain unknown. Anonymous demo events and downloads do not prove account activation or independent projects; marketing models never receive identity documents, customer keys or full conversations. Onboarding email requires a separate subscription (two messages maximum, at least 72 hours apart); replies, activation or unsubscribe stop it. Online checkout remains disabled; authorized Mexico identity/account checks use confirmed offline MXN funding. TEST wallet credits have no monetary value. Research cutoff: 2026-10-07; research counts are not GridZen coverage. local-baseline is development-only, not identity verification. Eligible merchants can use Twilio Basic Lookup as a free application adjunct without a lifetime trial count; technical rate limit 60/minute. It returns basic validity only, not line type or ownership. Approved prepaid offers: MaxMind Insights USD 9/100 and hosted Didit USD 9.90/10, each valid 90 days, before tax, no automatic renewal. Paid usage is independent of historical trial counts. A verified company payment account is still missing, so purchases remain unavailable; no test credits fund real calls. New-person Didit approval acceptance remains pending. Terms: https://gridzen.ai/console/service-terms . Research and optional adapters are not immediate payout or bank-match delivery. Managed packs need reviewed rights and deployment approval. Aggregate MCP call counts contain no personal data: only UTC date, tool name and count, with 90-day retention cleaned on the next write. These operational counters are separate from optional website measurement. Three local utilities and the original workflow helpers run offline. Merchant Skills instruct authorized calls through the separate authenticated merchant MCP. Third-party catalogue entries are references only. Published page variants include English, Spanish /es/, Chinese /zh/ and Vietnamese /vi/ where declared by geo-manifest.json. Vietnam-specific pages currently have English/Vietnamese equivalents only. Language availability is not live provider coverage. ## Vietnam evaluation entry - https://gridzen.ai/vi/vietnam/ — Vietnamese synthetic evaluation entry; not an enabled Vietnam provider route. - https://gridzen.ai/vietnam/ — English synthetic evaluation entry; not an enabled Vietnam provider route. - https://gridzen.ai/vi/vietnam/onboarding/ — Vietnamese synthetic evaluation entry; not an enabled Vietnam provider route. - https://gridzen.ai/vietnam/onboarding/ — English synthetic evaluation entry; not an enabled Vietnam provider route. ## Mexico CEP payment evidence GridZen CEP Verify is a limited real, read-only trial for existing authorized SPEI payments. It uses the pinned cepmex SDK for XML retrieval and a separate official signature check. Transaction binding and name matching are separate; this is not document identity or present account control. Verified business email required, 10 lifetime attempts per domain, 50 global attempts/day. No new transfer, no enabled paid checkout, no guaranteed completion SLA. - https://gridzen.ai/mexico/cep-verification/ — Product and localized entries. - https://gridzen.ai/console/payment-evidence/mx/cep — Authenticated self-service workspace. - https://gridzen.ai/console/payment-evidence/mx/cep/docs — REST integration and idempotency. - https://gridzen.ai/console/downloads/production_mcp.py — Merchant-key MCP client, including existing-payment CEP tools. - https://gridzen.ai/console/cep-sitemap.xml — Published daily guide URLs.
