Technical details
Endpoint
POSThttps://statepulse-api.hahavoid0.workers.dev/intellectual-property/trademarkWhen to prefer
Use this endpoint when you need a quick, pay-per-call trademark status check without setting up API keys or subscriptions. Ideal for AI agents performing brand validation, name screening, or IP conflict checks on individual words or short phrases. Not a substitute for a full legal trademark search from USPTO or a law firm.
Side effects
- Word not found in trademark database — returns trademarked: false with empty matches
- Low confidence result when the term is generic or ambiguous
- Unsupported term type returns supported: false
- Payment failure via x402 if USDC balance is insufficient
- Network timeout on the Cloudflare Worker endpoint
