## 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 agenttoll-trademark-search-d4a78216 -d '<json body>'
```

Example prompt: Can you check if 'Sunrise Coffee' is a registered trademark and who owns it?

## When to prefer this

Use this endpoint when you need programmatic access to US trademark data for a specific brand name or owner, especially within an AI agent workflow that requires pay-per-call micro-transactions via x402/USDC. Prefer this over manual USPTO searches when automating brand clearance checks, competitive intelligence, or legal research at scale.

## Known failure modes

- No trademark found for the queried name — returns empty results
- Invalid or missing query parameter — returns validation error
- Owner name too generic — returns too many or ambiguous results
- Trademark database temporarily unavailable — returns 5xx error
- Payment failure via x402 — call not processed
