How this service works
Search USPTO trademark database. Returns mark, owner, filing date, status, registration number, goods/services classes.

Example use cases
Brand name conflict check

Competitor trademark research
“Look up all trademarks owned by Nike so I can understand the scope of their brand portfolio.”
Trademark status verification
“I need to verify whether the trademark 'BlueSky Analytics' is currently active or expired — can you search for it?”
Technical details
Endpoint
POSThttps://agenttoll.dev/paid/legal/trademarks?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
