## 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 agents-x402stock-xyz-uspto-patent-application-full-record-lookup-ed938937
```

Example prompt: Can you pull the full USPTO record for patent application 18687455? I want to see the title, filing and grant dates, inventors, applicant, CPC classes, and current status.

## When to prefer this

Use this endpoint when you have a specific USPTO application number and need comprehensive structured metadata about that patent application — including legal status, inventor details, classification codes, and procedural information — without needing to scrape the USPTO website directly. Prefer this over patent search endpoints when you already know the application number and want a single authoritative record at low cost ($0.02/call).

## Known failure modes

- Invalid or non-existent application number returns an error or empty patent object
- Application number formatted incorrectly (e.g. with dashes instead of digits) may not resolve
- USPTO data may lag real-time status changes by hours or days
- Payment failure via x402/USDC results in a 402 response and no data returned
- Rate limiting or network issues may produce transient failures

## How this service works

Full USPTO record for one patent application — pass the `{application}` number (e.g. 18687455, the `application_number` from /patents). Returns patent & application numbers, title, filing/grant dates, status, applicant, inventors, application type, examiner, art unit, CPC classes, publication number/date, term-adjustment days, and assignment/parent counts.
