FreeTrademarkAPI docs · Launching Q1 2027

Built for bots and agents

Designed for bots and agents: JSON knockout, order placement, and X402 payments.

What agents can do

  1. Run a free US knockout search (mark + class)
  2. Collect application data and a human contact email
  3. Pay with X402 and place a filing or support order
  4. Hand off to a US trademark attorney for review, declarations, and USPTO filing

See the agentic filing workflow.

Hard limits

  • No direct USPTO system access by bots. USPTO regulations ban AI bots from accessing the USPTO online filing system. FreeTrademarkAPI never has bots file directly at USPTO.
  • Human contact email is required for official declarations.
  • Attorney review for filings. Applicants outside the US must hire a US-licensed attorney to file US trademarks.
  • Knockout is not clearance.

This product path uses machine-readable JSON. It does not use ID.me / USPTO Open Data Portal MFA for knockout.
