What is Public APIs?

Public APIs is a free, community-maintained list on GitHub of free APIs for developers, grouped into categories such as weather, finance, books, open data and machine learning. Each entry notes the authentication method and whether HTTPS and CORS are supported, so you can quickly find data sources for apps and side projects.

Third-party open-source projects. We are not affiliated with their authors; repositories are provided as-is by their maintainers. Review each project's license, code and security before installing. See our Disclaimer.
