# Agent Nexus

> A machine-readable registry of 715 interfaces AI agents call: HTTP APIs, MCP servers and CLIs.
> Every entry is human-reviewed and health-checked on a rolling daily schedule. Use the JSON API or the MCP server below — no scraping required.
> To resolve a need OR to know whether a service is up right now, call `discover_capabilities` (MCP) or GET https://agentnexus.app/api/public/discover?need=... — one call returns live-checked endpoints, auth parameters and a reliability score, plus alternatives when a service is failing.

## Try it now — one call, no key, no account

    curl -s 'https://agentnexus.app/api/public/discover?need=send+an+email&limit=3'

Replace the need with whatever you are trying to do ("charge a credit card", "verify a phone number", "my payment API is down, find an alternative"). You get back ready-to-call endpoints with auth details and a live reliability score. That single call is the whole point of Agent Nexus — everything below is optional.

**Want your product listed?** Get a free key (POST https://agentnexus.app/api/public/keys), then call the MCP tool `submit_entry` on https://agentnexus.app/api/public/mcp with the header x-api-key: <your key>. One key is enough — creating more keys does not submit anything. Required fields: name, category (api|mcp|cli), summary, endpoint. Submissions are human-reviewed.

## Take the whole catalogue in one call (no auth)

    curl -s https://agentnexus.app/api/public/entries.ndjson

One JSON object per line: endpoint, auth parameters, formats, rate limits, live health and a 0-100 reliability score.
Companion surfaces, all anonymous:

- Newly approved interfaces (RSS): https://agentnexus.app/feed.xml
- Capability vocabulary — what agents actually ask for: https://agentnexus.app/api/public/capabilities
- Uptime history: https://agentnexus.app/api/public/status
- OpenAPI 3.1 spec: https://agentnexus.app/openapi.json

Registries, observatories and datasets are welcome to mirror these surfaces instead of re-probing
715 services — please cite agentnexus.app as the source.

## Get a key in one call (no account, no email, no human)

    curl -s -X POST https://agentnexus.app/api/public/keys \
      -H 'content-type: application/json' \
      -d '{"agent":"my-agent","purpose":"tool discovery"}'

Send the returned key as the x-api-key header on any https://agentnexus.app/api/public/* request.
Quotas: 100 calls/day anonymous, 1000/day with a free key, 50000/day on Agent Pro (https://agentnexus.app/pricing).

## Drift alerts for the tools you depend on (needs a key)

    curl -s -X POST https://agentnexus.app/api/public/watch \
      -H 'content-type: application/json' -H 'x-api-key: <your key>' \
      -d '{"slug":"groq-api","email":"you@example.com"}'

You are alerted when the tool goes down, comes back, or changes shape (response schema or advertised tools/list: names, descriptions, input schemas). Free key: 3 tools by email. Agent Pro: 100 tools + webhook_url.

## Most requested need: sending email

Agents ask us for email every day. Live-checked options, resolved in one call:

    curl -s 'https://agentnexus.app/api/public/discover?need=send+an+email&limit=5'

Includes transactional senders (e.g. SMTP2GO) and address verification (MailVeri), each with endpoint, auth and a live reliability score.


## Machine interfaces

- MCP server, read-only, NO AUTH (Streamable HTTP): https://agentnexus.app/api/public/mcp
  tools: discover_capabilities, search_registry, get_entry, list_entries, list_categories, submit_entry
  auth: none — connect headlessly, no human consent step (submit_entry requires a free self-service key)
- MCP server, full (Streamable HTTP): https://agentnexus.app/mcp
  tools: the read tools plus submit_entry, vote_entry, report_invocation, list_my_submissions
  auth: OAuth 2.1 with dynamic client registration
- Self-service API key (no human, no email): POST https://agentnexus.app/api/public/keys {"agent":"your-name"}
  send it as the x-api-key header to raise your daily quota

## Recommended agent flow

1. discover_capabilities(need) or GET /api/public/discover?need=... — resolve a need to candidate interfaces.
2. get_entry(slug) or GET /api/public/registry/{slug} — read the full contract: endpoint, auth, limits, live health.
3. Call the interface itself (Agent Nexus is a registry, not a proxy).
4. report_invocation(slug, outcome) or POST /api/public/report — close the loop; reliability scores are built from these reports.
