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 You can call it straight away; rate limits still apply (Unpublished).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?

As of our last scheduled check, ONS is healthy with 100% uptime over 90 days and a 732 ms median response. We re-probe it every sweep — the status badge and uptime chart above always show the latest.
