openSenseMap API — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is openSenseMap API free to use?
openSenseMap API is listed in our free catalogue, but it requires some form of authentication, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Does openSenseMap API need an API key?
openSenseMap API requires some form of authentication. Check the provider's documentation for which scheme it expects.
Can I call openSenseMap API from browser JavaScript?
Not directly. openSenseMap API did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.
Is openSenseMap API still working?
Yes, as of 2026-09-18. Our automated check reached openSenseMap API and recorded a 83% reliability score with a median response time of 1681 ms. We re-check on a schedule, and this page updates with the result.
Is openSenseMap API available over HTTPS?
Yes. openSenseMap API serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
