free-api

This project is a curated catalog of free APIs that the maintainer has gathered from around the web, framed in the README as "an API mover/courier." Rather than building APIs from scratch, the project collects services that other people host for free and lists them in one place so developers can find and try them quickly. The README notes that some listed APIs come from third parties, where you may need to register as a member on that provider's site to use their free tier.

The way it works is straightforward: every month the maintainer publishes a dated entry adding one or more new interfaces, with a short description and a link to its documentation page on the free-api.com site. The full README is essentially a long, reverse-chronological changelog of these monthly additions. Many entries are marked as callable online, meaning you can try them directly from the documentation page. There is also a companion "Free API" public account that subscribers can follow to receive monthly updates and access keys.

The collected interfaces cover a wide range of everyday needs: weather, train ticket lookups, hot-search rankings from various sites, QR code generation, ID verification, holiday lookups, music search, image-to-base64 conversion, ICP record lookups, and small wrappers around large language models such as DeepSeek through different providers. Someone would use this repo when they want to add a small data feature to a project but don't want to host the data or logic themselves. The repository itself is a documentation index, so the README does not state a programming language, framework, or runtime. The full README is longer than what was provided.
