Frequently asked questions

Are all these APIs really free?

Each one has at least a free tier or is entirely free to use, but many still require a free API key (shown in the "Auth" field) and some free tiers have request-rate limits. Always check the linked docs for the current terms before building on any of them.

Where does this data come from?

From the open-source, MIT-licensed "public-apis/public-apis" project on GitHub — one of the most popular community-maintained API lists, with 450k+ stars. This directory is a snapshot; new APIs are added to the source project regularly.
