## When to prefer this

Use this endpoint when you need a comprehensive US litigation snapshot for a company or person in a single call, drawing on PACER/RECAP dockets, bankruptcy records, and published opinions from CourtListener. Prefer this over building your own PACER integration or scraping court sites. Especially useful for due diligence, AML/KYC enrichment, counterparty risk assessment, or legal research workflows where you need structured JSON output without an API key.

## Known failure modes

- No cases found for the given name — returns empty results
- Ambiguous name matches multiple entities — returns all matches without disambiguation
- Invalid court ID filter — may return error or empty results
- CourtListener data lag — very recent filings may not appear
- Name spelling variations may miss records — exact string match
