Air Quality API — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Air Quality API free to use?
Air Quality 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 Air Quality API need an API key?
Air Quality API requires some form of authentication. Check the provider's documentation for which scheme it expects.
Can I call Air Quality API from browser JavaScript?
Yes. Air Quality API returned CORS headers when we checked it, so a browser will let your page read the response. You can fetch it directly from client-side JavaScript with no proxy and no backend.
Is Air Quality API still working?
Yes, as of 2026-09-18. Our automated check reached Air Quality API and recorded a 100% reliability score with a median response time of 93 ms. We re-check on a schedule, and this page updates with the result.
Is Air Quality API available over HTTPS?
