How this service works
50 pay-per-call tools for AI agents: web scraping, markdown downloads, disposable inboxes, webhooks, domain verification, and registry lookups. x402 USDC on Base, no API key.
Output
Returns a JSON object with the queried name, a list of matching trademark marks and their owners, a boolean conflict flag, a confidence level (e.g. 'high'), the data freshness date (e.g. '2026-06'), and a disclaimer that results are informational only and not legal advice.
Example use cases
Verify startup brand name availability
“I'm launching a new SaaS product called 'CloudVault' and need to know if that name is already trademarked or if there are any similar marks that could create legal issues for us.”
Screen product names before launch
“We're considering three product names for our new line: 'NeonFlow', 'PulseSync', and 'VortexAI'. Can you quickly check if any of these are already registered trademarks or have conflicts?”
Audit trademark conflicts during acquisition
“We're about to acquire a company that uses the brand name 'EchoLink'. Before closing the deal, I need you to search the trademark registry and tell me if that name is already trademarked by someone else or if there are any potential conflicts.”
Technical details
Endpoint
POSThttps://codepulse-api.hahavoid0.workers.dev/intellectual-property/trademark?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call trademark conflict check without signing up for an API key. Ideal for AI agents performing brand name due diligence, startup naming workflows, or IP screening. Prefer this over manual USPTO searches when automation and cost-per-query pricing ($0.001 USDC) are priorities. Not a substitute for formal legal advice or a registered IP attorney.
Side effects
- Name not found in registry returns empty matches array with conflicts:false
- Unsupported jurisdiction or trademark class may return supported:false
- Ambiguous or very short names may return low confidence score
- Network or upstream registry timeout may return HTTP 5xx
- Payment not processed (x402 USDC) results in 402 Payment Required
