About Public API Lists
Public API Lists is a GitHub repository containing a hand-curated list of more than 730 free public APIs, grouped into 48 categories. The list can be browsed and searched on the project website, and the same data is available through a JSON API. The project is community-maintained and is open source. Contributions are handled through a contributing guide.
Each entry shows the API's description, its authentication type, and whether it supports HTTPS and CORS. Many entries require an API key or OAuth, and some HTTPS or CORS values are marked as unknown, so users should check each API's requirements before relying on it. The project is maintained by volunteers, and sponsorship is described as helping keep the list maintained.
