## 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 suverse-federal-register-search-6fa05041 -d '<json body>'
```

Example prompt: Search the US Federal Register for documents related to 'stablecoin regulation' and show me the titles, document types, agencies, and publication dates of what comes up.

## When to prefer this

Use this endpoint when you need fast, keyless access to US Federal Register documents for regulatory monitoring, compliance research, or policy tracking — particularly when you need to search by free-text keyword across all document types (rules, proposed rules, notices, executive orders) and want structured metadata like agency and publication date back. Prefer this over direct Federal Register API calls when operating in an agentic x402 payment context.

## Known failure modes

- Empty results if search term is too obscure or misspelled
- Overly broad results if search term is too generic
- Service timeout if upstream Federal Register API is unavailable
- Malformed request body returns 400 error
- Rate limiting or payment failure returns 402 error

## How this service works

## Output

Returns a list of Federal Register documents matching the search term, each including the document title, document type (rule, proposed rule, notice, executive order, etc.), the publishing agency, and the publication date.
