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 quant-agent-shop-patent-search-29f1a994 -d '<json body>'
```

Example prompt: Can you search for patents related to solid-state battery sulfide electrolytes, filtering to US patents in English? I want to see what prior art exists before we file.

## When to prefer this

Choose this endpoint when you need quick, structured patent data from Google Patents without setting up a full Google Patents API integration. It is ideal for prior-art reconnaissance, competitor IP monitoring, and technology landscape research where you need bibliographic metadata and PDF links in a single fast call. Prefer it over raw web scraping when you need reliable structured fields (dates, assignee, inventor, publication number) rather than unstructured HTML.

## Known failure modes

- Query too short (under 2 characters) or too long (over 400 characters) returns a validation error
- Invalid country code format (not lowercase two-letter) returns a validation error
- Invalid language code format returns a validation error
- Page number outside range 1-5 returns a validation error
- No matching patents found returns an empty results array
- Google Patents/Serper downstream outage may return a service error; failed calls are not charged
- Network timeout on unusually complex queries

## How this service works

Patent search. Send keywords, a technology description or an assignee name; returns up to 10 Google Patents results with title, publication number, priority, filing, grant and publication dates, inventor, assignee, snippet and PDF link. Use for prior-art scans and competitor patent checks. Not legal advice. Typical response about 1 s. Failed calls are not charged.

## Output

Returns a JSON object containing the original query, the source attribution (Google Patents via Serper), a timestamp, and an array of up to 10 patent records. Each record includes: patent title, Google Patents URL, PDF download URL, a text snippet, assignee, inventor, language, position in results, grant date, filing date, priority date, thumbnail URL, publication date, and publication number.
