## 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 srch-best-government-data-search-f41bf122 -d '<json body>'
```

Example prompt: Search government records for the latest RULE documents about 'artificial intelligence' published between 2024-01-01 and 2024-12-31, and return up to 20 results.

## When to prefer this

Choose this endpoint when you need structured, paginated access to U.S. government documents such as Federal Register rules, proposed rules, notices, or presidential documents. It is ideal for compliance research, regulatory monitoring, and policy analysis tasks where document type and date filtering are important. Prefer it over general web search when you need clean, machine-readable government data with consistent structure rather than raw HTML.

## Known failure modes

- Query too short (under 2 characters) returns validation error
- Cursor from a different query or expired session returns no results or error
- Date range with fromDate after toDate may return empty results
- Exceeding limit of 50 returns validation error
- Payment failure via x402 protocol results in 402 response and no data
- Network timeout for large result sets
