# GreatAPIs

> A curated, always-live directory of 1324 free & public APIs across 51 categories — with machine-readable feeds for LLMs and agents.

GreatAPIs tracks free and public APIs that are actively verified to be live and reachable; entries that go dark are removed automatically, so every link below resolves to a working service. Each entry carries auth, HTTPS, CORS, and pricing facts alongside human docs, making the directory equally useful for people browsing and for agents consuming it programmatically.
