Example prompt: Search Google Patents for recent patents related to transformer neural network architectures filed after 2020 and return the top results including titles, patent numbers, and assignees.

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to Google Patents search results without managing a subscription or API key. Ideal for agents that infrequently query patents and prefer micropayment-based access. Use when you need SERP-style patent search results including titles, abstracts, inventors, and assignees from Google's patent index.

## Known failure modes

- Payment failure or insufficient USDC balance returns 402 Payment Required
- Invalid or malformed query parameters return upstream error
- No results found for highly specific or obscure queries
- Rate limiting or upstream Google Patents scraping errors cause 5xx responses
- Malformed JSON body results in request forwarding failure
