Use this endpoint when you need detailed structured patent data from Google Patents on a pay-per-use basis without a long-term SerpApi subscription, especially in agent workflows where on-demand patent lookup is needed at low cost ($0.01/call) via x402 crypto micropayment.

## Known failure modes

- Invalid or malformed patent ID returns empty or error response from upstream
- Payment failure due to insufficient USDC balance results in 402 status
- Upstream SerpApi unavailability causes gateway timeout or 5xx error
- Malformed path or query parameters result in no data returned
- Rate limiting by upstream provider may return error responses
