Free Pharma APIs — common questions
Counts and timings below come from our own scheduled checks of this category.
How many free pharma APIs are there?
We track 1 in this category, of which 0 responded at our last check. 1 of them need no API key.
Which pharma APIs work without an API key?
1 of the 1 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 pharma APIs in a browser app?
1 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.
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, 483 of 2,737 entries were not responding at the last full run, which is the sort of thing an unchecked list never tells you.
