Public APIs¶

1,816 free public APIs, across 51 categories — searchable, documented, and organized so you can find the right one in seconds instead of scrolling a 2,000-line README.

This site is a documentation-as-code companion to the community-curated public-apis GitHub project: the same data, restructured into a searchable reference with one page per category.

Browse by category

All 51 categories, from Animals to Weather, each with API name, auth type, HTTPS and CORS support.

What's in here¶

Every API is listed with the same five fields used by the source project, so nothing is lost in translation:

Field	What it tells you
API	Name, linked to its homepage or docs
Description	One line on what it does
Auth	`No`, `apiKey`, `OAuth`, `X-Mashape-Key`, or `User-Agent`
HTTPS	Whether it's served over HTTPS
CORS	Whether it's callable directly from browser JavaScript

See How to read the tables for the full explanation.

About this site¶

This is an independent documentation build — not an official product of the public-apis maintainers or APILayer. All API data is sourced from the public-apis README, MIT licensed, and reproduced here in a searchable, per-category format. Found an error or want to add an API? Contributions go to the source project, not this site — this site rebuilds from it.
