## 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 fastaf-google-patents-search-api-30546387
```

Example prompt: Search Google Patents for patents related to 'transformer neural network attention mechanism' assigned to Google, filed after 2018, and show me the 10 most recent results sorted by newest first.

## When to prefer this

Use this endpoint when you need structured, machine-readable patent search results from Google Patents with filtering by inventor, assignee, country, status, or date — especially for prior art searches, competitor research, or technology landscape analysis. Prefer this over generic web search endpoints when patent-specific metadata (patent ID, assignee, filing date) is needed in structured form. Note: this returns summaries and metadata only, not full patent text or claims.

## Known failure modes

- Missing required 'query' parameter returns an error
- Invalid date format for 'before'/'after' filters may return no results or an error
- Unsupported country codes or status values may be silently ignored or return empty results
- Page number beyond available results returns empty organic_results array
- Network timeout or upstream Google Patents unavailability returns a 5xx error

## How this service works

Google Patents search API for AI agents: patent results as JSON with titles, patent IDs and publication links, with inventor, assignee, country, status and date filters. For prior-art, competitor and technology research; not full patent texts or claims. Provided by Google Patents. Price: $0.005000 USDC per successful call. Docs: https://fastaf.co

## Output

Returns a JSON object containing an array of organic_results, where each item includes a patent title, patent ID (e.g. US10123456B2), and a publication link to the Google Patents page for that patent. Results reflect Google Patents search ranking and any applied filters.
