No dead links

Every API was probed live on 7 Oct 2026. Old 'awesome API' lists are full of endpoints that moved or now need a key.

Browser-ready

The CORS column tells you which APIs you can call straight from a web page, with no proxy.

Copy, paste, done

Each row has curl and fetch code, so you go from idea to working request in seconds.

Questions

Good to know

Will these APIs keep working?

They all worked when probed on 7 Oct 2026, but public APIs change. The README explains the probe so you can re-check any of them yourself.

Can I use this commercially?

You can use the Atlas in your own work. Each API has its own terms, linked in the docs column, so check them before shipping.

Which categories are covered?

21, including Dev, Fun, Geo, Government, Science, Finance, Food, Weather, Transport, Books, Health and Language.

What if it doesn't work for me?

If it doesn't work as described or you can't access it, email us within 14 days and we'll fix it or refund you. See the refund policy for details.
