IPMA: common questions

Is IPMA free to use?

Yes — IPMA is a free weather API. Free tier: Free, no key. Whether the free tier allows commercial use is unclear — check the provider docs.

Does IPMA need an API key?

No — IPMA needs no API key or signup. You can call it straight away; rate limits still apply (Unpublished).

Can I call IPMA from the browser?

Yes — IPMA returns CORS headers over HTTPS, so front-end code can fetch it directly with no backend proxy. Use the fetch snippet on this page, or hit "Run live" to try it now.

Is IPMA up right now?

IPMA is catalogued but not yet on our probe schedule, so we don't publish a live status for it. Check the provider's own status page or docs for its current state.
