Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability statepulse-api-patent-lookup-585d4a58 -d '<json body>'
```

Example prompt: Can you look up the patent for 'Coherent Light Source' and tell me the patent number, who the inventors are, and when it was filed?

## When to prefer this

Use this endpoint when an AI agent needs to quickly retrieve structured patent metadata — including inventors, filing date, and patent number — without setting up API keys, and is willing to pay $0.12 USDC per call via x402 on Base. Ideal for lightweight IP research tasks embedded in automated workflows.

## Known failure modes

- Patent not found in database — result may be empty or unsupported flag set to false
- Ambiguous query returns low-confidence result
- Invalid or malformed patent number input causes error response
- Network timeout on the Cloudflare Workers edge
- Rate limiting or payment failure via x402 USDC

## 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.
