Counts and timings below come from our own scheduled checks of this category.
We track 60 in this category, of which 45 responded at our last check. 5 of them need no API key.
5 of the 60 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.
3 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.
Of the keyless options that responded at our last check, Vector Express v2.0 was quickest at a median 1345 ms. Speed is only one factor — coverage and licensing usually matter more — but it is measured here rather than claimed.
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, 361 of 3,005 entries were not responding at the last full run, which is the sort of thing an unchecked list never tells you.
