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 agenttoll-patent-search-fedcc6dd -d '<json body>'
```

Example prompt: Search for patents related to 'transformer neural network architecture' and return the top 10 results so I can review prior art before filing.

## When to prefer this

Choose this endpoint when you need pay-per-call patent data without a subscription to expensive IP databases like USPTO APIs or commercial patent platforms. Ideal for AI agents performing one-off prior art searches, competitive intelligence, or IP landscape analysis where cost-per-query matters. Best suited for keyword-based patent discovery rather than structured legal filing workflows.

## Known failure modes

- Empty results if query terms match no patents
- Malformed or overly broad queries may return irrelevant results
- Rate limiting or payment failure if USDC balance is insufficient
- Service unavailability returning a non-success response
- Invalid limit parameter causing request rejection

## How this service works

108+ receipt-backed x402 work products for AI agents. Clear prices, spend caps, buyer metadata, and structured results over Base USDC.

## Output

Returns a JSON object containing an array or object of patent records matching the query, along with metadata including the total count of results, the data source, and a timestamp of when the data was generated. A boolean 'cached' field indicates if results are from cache, and 'success' confirms the request status.
