## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability patentpulse-patent-status-lookup-3b2b8717
```

Example prompt: Can you pull up the full details on US patent number 10,123,456 — I need the legal status, estimated expiry date, years remaining, inventors, assignees, and the CPC classifications?

## When to prefer this

Use this endpoint when you need comprehensive US patent details including legal status, expiry estimates, and classification data for a specific known patent number. Prefer this over trademark search sibling endpoint when dealing with patents rather than trademarks. Ideal for IP agents, patent attorneys, and innovation analysts needing structured patent metadata without scraping USPTO directly.

## Known failure modes

- Invalid or malformed patent number returns a 400 error
- Patent number not found in database returns a 404
- Payment not included or insufficient USDC returns a 402
- Rate limit exceeded returns a 429
- Service unavailable returns a 503
