How this service works
50 pay-per-call tools for AI agents: live telemetry, environmental, transit, blockchain, network/security and finance utilities. x402 USDC on Base, no API key.
Output
Returns a JSON object with the patent's filing date, title, list of inventors, patent number, a supported flag indicating whether the query type is handled, and a confidence level (e.g. high/medium/low) for the result.
Example use cases
Verify invention patent ownership
“Can you check if there's a patent for 'noise-canceling headphones' and tell me who the inventors are and when it was originally filed?”
Retrieve patent number for product
“I need to find the patent number and filing date for the lithium-ion battery — can you look that up and give me the full list of inventors too?”
Check patent existence for technology
“Does a patent exist for 'CRISPR gene editing'? If so, what's the patent title, who filed it, and what's the patent number?”
