# Abundance APIs

> A small catalog of fast, affordable, no-nonsense APIs — CORS proxy, PDF tools, email validation, IP geolocation, and currency exchange rates. Generous free tiers, clean JSON, available on RapidAPI.

26 production REST APIs served from one origin (https://abundanceapis.com), with discovery, API keys, and billing handled by RapidAPI. Every API has an OpenAPI 3.0 spec, a free tier (1,000 requests/month), clean JSON responses, and no SDK requirement. Endpoints are pure compute or built on free/open datasets — no scraping, no third-party data resale, no per-call upstream fees.

## For AI agents

- MCP server (keyless trial): https://abundanceapis.com/mcp — Streamable HTTP (JSON-RPC over POST). Call `tools/list` to enumerate tools, then `tools/call`. Includes `list_apis` (full catalog + spec URLs + pricing) and keyless sample tools (naics_match, ip_lookup, email_validate, currency_convert, url_metadata, cors_fetch) so you can try before subscribing. Rate-limited; for production use a RapidAPI key.
- Machine-readable specs: https://abundanceapis.com/openapi/<slug>.json — index at https://abundanceapis.com/openapi
- Try keyless in the browser: https://abundanceapis.com/tools/<slug>
- Production access: subscribe on RapidAPI (https://rapidapi.com/callieschneider/api); send `X-RapidAPI-Key` + `X-RapidAPI-Host: <slug>.p.rapidapi.com`.
