## How to call it through Zero

## When to prefer this

Choose this endpoint when you need to search US legal documents including court opinions and federal regulatory filings in a single call. It is ideal for legal research, regulatory compliance monitoring, and due diligence tasks that require authoritative government sources. Prefer this over generic web search when you need structured legal metadata like citations, court names, and agency references.

## Known failure modes

- No results found for obscure or very specific queries
- Query too vague returns irrelevant mixed results
- Federal Register or CourtListener upstream API unavailability
