## How to call it through Zero

Example prompt: Can you run a trademark clearance search for the brand name 'BloomCraft' in the US for goods in Class 25 (clothing) — I need to know if there are any confusingly similar marks already registered, the USPTO status, and what the opposition risk looks like before I file?

## When to prefer this

Use this endpoint when an IP agent, brand agent, or startup advisor needs to assess trademark availability and clearance risk before launching a brand or filing a trademark application. Preferred over generic web search for trademark research because it provides structured USPTO/TESS data, confusion analysis, and actionable filing strategy in a single call.

## Known failure modes

- Mark name not provided — returns 400 bad request
- Goods/services class not recognized — returns validation error
- USPTO/TESS database temporarily unavailable — returns 503
