Noctua: common questions

Is Noctua free to use?

Yes — Noctua is a free science & space API. Free tier: Free — limits not published. Whether the free tier allows commercial use is unclear — check the provider docs.

Does Noctua need an API key?

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 You can call it straight away; rate limits still apply (Unpublished).

Can I call Noctua from the browser?

Not directly — Noctua doesn't send browser-friendly CORS headers, so call it from a server or proxy instead. Copy the curl or Python snippet on this page to get started.

Is Noctua up right now?

Noctua 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.
