## 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 2s-io-uspto-trademark-search-0d4c5941
```

Example prompt: Can you search the USPTO trademark register for live trademarks with the wordmark 'Sunrise' in Nice class 25 (clothing), and show me the owner, status, filing date, and goods/services for each result?

## When to prefer this

Use this endpoint when you need to search the USPTO trademark register by text (wordmark, owner, or goods/services) — a capability the USPTO itself offers no public API for. Prefer this over law.trademark-status when you don't have a known serial number and need discovery/search. If you already have a serial number and need detailed prosecution history, use the sibling law.trademark-status endpoint instead.

## Known failure modes

- No results found for query — trademark not in USPTO register or search terms too specific
- Invalid serial/registration number format — returns error or empty result
- Invalid intlClass value — filter silently ignored or returns error
- Query too vague — returns many irrelevant results; refine with field or intlClass filters
- Rate limit or payment failure — x402 payment not processed, returns 402 status

## How this service works

Search US trademarks by wordmark text, owner name, or goods/services — the text search the USPTO offers no public API for. Pass `query` for full-text search (ranked best-match first), or `serial` / `registrationNumber` for an exact record. Filter with `field` (mark|owner|all), `status` (live=registered+pending only, default; all=includes dead/abandoned), and `intlClass` (Nice class, e.g. 9). Returns each mark's wordmark, serial, registration number, status (+ live flag), filing/registration/abandonment dates, owner, international classes, and goods/services. Corpus: USPTO full trademark register (public domain). Use law.trademark-status for live USPTO prosecution detail on a known serial.

## Output

A ranked list of trademark records, each containing: wordmark text, USPTO serial number, registration number, current status (registered/pending/abandoned/etc.) with a live boolean flag, filing date, registration date and/or abandonment date, owner name, Nice international class(es), and goods/services description. Results are ranked by relevance for full-text queries, or return a single exact record for serial/registration number lookups.
