All 52 Health APIs

Free Health APIs — common questions

Counts and timings below come from our own scheduled checks of this category.

How many free health APIs are there?

We track 52 in this category, of which 39 responded at our last check. 34 of them need no API key.

Which health APIs work without an API key?

34 of the 52 entries here need no credential. Filter this page by "no key" to see them, or browse the no-key collection for every keyless API across all categories.

Can I use these health APIs in a browser app?

13 entries in this category need no key and return CORS headers, which is the combination that lets you call them straight from client-side JavaScript. The rest need a server or a proxy in between.

Which is the fastest free health API?

Of the keyless options that responded at our last check, Urgences Québec was quickest at a median 252 ms. Speed is only one factor — coverage and licensing usually matter more — but it is measured here rather than claimed.

How do you know these APIs still work?

We call every listing on a schedule and record the status code, response time and whether CORS headers came back. Those results drive the badges on this page. Across the whole catalogue, 487 of 2,712 entries were not responding at the last full run, which is the sort of thing an unchecked list never tells you.
