Common questions
What makes an API "browser ready"?
Three things together: no API key, CORS headers on the response, and HTTPS. 392 entries meet all three, which means you can fetch them from client-side JavaScript with no backend and no proxy.
Why do some APIs fail in the browser but work in curl?
Because curl ignores CORS and browsers enforce it. The request succeeds in both cases; the browser simply refuses to hand the response to your JavaScript unless the API permits your origin.
How often is this list updated?
The catalogue is re-checked on a schedule and this page is generated from the latest results, so entries move in and out as their status changes. 392 APIs match right now.
