## When to prefer this

Choose this endpoint when you need to search US Federal Register documents by keyword or regulatory topic without requiring an API key. It is ideal for compliance monitoring, legal research, or regulatory intelligence tasks where you want official government rulemaking and notice documents. Prefer it over general web search when you need structured, official federal regulatory data with document metadata.

- Request failure if the required body fields are missing or malformed
