Stable. No schema drift observed since monitoring began — the response shape has not changed under our checks.

USPTO: common questions

Is USPTO free to use?

Yes — USPTO 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 USPTO need an API key?

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 You can call it straight away; rate limits still apply (Unpublished).

Can I call USPTO from the browser?

Not directly — USPTO 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 USPTO up right now?

As of our last scheduled check, USPTO is unmonitored. We re-probe it every sweep — the status badge and uptime chart above always show the latest.
