Free Phone APIs — common questions

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

How many free phone APIs are there?

We track 8 in this category, of which 8 responded at our last check. 1 of them need no API key.

Which phone APIs work without an API key?

1 of the 8 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 phone APIs in a browser app?

None of the entries in this category currently combine no-key access with CORS headers, so you will need a small server-side proxy to use them from browser JavaScript.

Which is the fastest free phone API?

Of the keyless options that responded at our last check, Phone Specification was quickest at a median 913 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.
