About

FreeAPIRadar gathers free public APIs — no-key APIs, free-tier services and freshly published OpenAPI specs — across AI, weather, finance, maps and more on one page.

Every item links to its official directory listing, where you can read reviews, check permissions and install it.

The list refreshes every hour. The site is free to use and funded by unobtrusive advertising.

Some outbound links may earn us a commission. It never changes the price you pay, and it never decides what we list.
