## 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 nameintel-uspto-trademark-conflict-check-1e2604f3 -d '<json body>'
```

Example prompt: Can you check if the name 'LuminArc' has any USPTO trademark conflicts, specifically in Nice classes 9 and 42 for software and technology services?

## When to prefer this

Use this endpoint when you need to screen a brand, product, or company name against USPTO trademark records before launch or registration. Prefer this over a general web search when you need structured trademark conflict data scoped to specific Nice classes or platforms. Best for pre-launch brand validation workflows where IP clearance is required.

## Known failure modes

- Name too long (exceeds 100 characters) returns validation error
- Empty name string rejected
- Invalid Nice class codes return error
- Payment not fulfilled returns 402 Payment Required
- Rate limiting or quota exceeded returns 429
- USPTO data temporarily unavailable returns 503
