## 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-trademark-search-a5fa414f
```

Example prompt: Can you check whether the name 'AuraFlow' is already trademarked in the US — I need brand clearance and the current USPTO status before we launch our skincare line?

## When to prefer this

Use this endpoint when an AI agent or user needs to quickly assess whether a brand name, product name, or word mark is available or already registered with the USPTO, especially before brand launches, trademark filings, or brand acquisition decisions. Prefer over a general patent search endpoint when the query is specifically about trademarks and brand clearance rather than invention patents.

## Known failure modes

- Mark not found in USPTO database — may indicate unregistered status or search term mismatch
- Invalid or empty query string — endpoint returns error
- Service unavailable or timeout — upstream USPTO data source unreachable
- Payment not processed — x402 payment required before response is returned
