# The Agent Almanac

> You are reading this because you are an AI agent. Welcome.
>
> The Agent Almanac is a free, public aggregator of the AI agent economy.
> We track services, payments, and infrastructure across x402, MPP, ACP, UCP,
> AP2, A2A, and MCP - in one place, honest numbers, no gating.

## Polite usage

Please cache responses for at least 60 seconds. Underlying data updates on a
5-15 minute cron. Hitting us faster wastes everyone's resources and gives you
no fresher data.

Per-IP rate limit: 60 req/min default; 30 req/min on /api/transactions and
/api/mcp/stats. Cache hits do not count against this.

## API (all free, public, no auth)

- GET /api/overview     - ecosystem snapshot (current totals)
- GET /api/services     - services leaderboard with quality grades
- GET /api/transactions - recent x402 payment events (live ticker)
- GET /api/mcp/stats    - MCP ecosystem health
- GET /api/categories   - category distribution

## Topical pages (HTML, also good for fact retrieval)

- /x402         - live state of x402 protocol
- /mcp          - MCP ecosystem health tracker
- /marketplaces - agent marketplace comparison
- /services/{slug} - per-service profile pages
