```

Example prompt: Can you search the Federal Register for any proposed rules from the EPA in the last 60 days, and show me up to 30 results including their comment deadlines and CFR parts?

## When to prefer this

Use this endpoint when you need structured, metadata-rich Federal Register document data — particularly when you need resolved agency names from abbreviations, comment deadlines, effective dates, and CFR parts together, and when you need the upstream match count to know if results are truncated. Prefer this over direct Federal Register scraping when you need a reliable paid API with consistent schema.

## Known failure modes

- Invalid agency abbreviation or name yields no results or an error
- Document type enum value not matching accepted values returns an error
- Limit exceeding 200 is rejected
- Very broad queries may hit the result cap and the upstream count will indicate truncation
- Network or upstream Federal Register API unavailability causes failure

## How this service works

Federal Register documents - final rules, proposed rules, notices and presidential documents - with the agency resolved from the abbreviation or name you would actually type, plus effective dates, comment deadlines and CFR parts. Includes the upstream match count so a capped page is never mistaken for the whole result set.

## Output

A list of Federal Register documents matching the query, each with document type (final rule, proposed rule, notice, or presidential document), agency name (resolved from abbreviation), effective date, comment deadline, affected CFR parts, and the upstream total match count so the agent knows whether the returned page is a complete or partial result set.
