ONS: common questions

Is ONS free to use?

Yes — ONS is a free government API. Free tier: Free — limits not published. Whether the free tier allows commercial use is unclear — check the provider docs.

Does ONS need an API key?

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 You can call it straight away; rate limits still apply (Unpublished).

Can I call ONS from the browser?

Yes — ONS 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 ONS up right now?

ONS 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.
