Search public APIs — with auth details and Postman guides
FindAnAPI.com is a searchable directory of public APIs, built and maintained by a single developer as an independent side project — not a company, not a team, just one person who kept a running list of useful APIs and decided to make it public.
Every entry documents the practical things you actually need before integrating an API: authentication type, base URL, pricing tier, a working sample request, and — where useful — a ready-to-import Postman collection. Entries are sourced from public API directories and provider documentation, then organised and enriched (sector tagging, auth normalisation, use-case notes) rather than published as a raw, unedited dump.
Live status matters more than a one-time listing: an hourly uptime check measures each catalog API directly from our own monitor — not provider claims — and that data drives real up/down and response-time figures on comparison pages and the Reliability Rankings, which rank every category by measured 7-day uptime. A periodic dead-link sweep separately flags entries whose documentation URL has moved or disappeared.
The tools linked from the Apps page — VIN decoding, product recall search, drug safety lookups, case law search, and more — aren't a separate product. Each one is a small, complete example of an API from the catalog actually being used for something real, built specifically to prove the listing underneath it is worth your time. If you're evaluating whether an API in this catalog is any good, the linked app for it (where one exists) is the fastest way to find out.
The site is static — generated from a Supabase database and deployed to Cloudflare Pages — with a handful of small Cloudflare Workers handling scheduled ingestion, uptime checks, and CORS proxying for APIs that don't set browser-friendly headers. There's no backend server to log in to and no user accounts; what you see is what's generated at build time.
