## When to prefer this

Choose this endpoint when an agent needs synthesized, relevance-ranked federal case law with citation metrics and precedential status for a specific legal topic, especially when verifiability via cryptographic signing matters. Prefer over raw court database queries when you need ML-ranked results with citation counts rather than unranked docket lookups. Best for litigation research, compliance gap analysis, and legal due diligence workflows.

## Known failure modes

- Vague or overly broad topic returns low-relevance cases
- Unknown or malformed court identifier returns no results or error
- date_after in wrong format (not YYYY-MM-DD) returns validation error
- limit exceeding maximum of 20 causes request rejection
- Topic with no matching opinions returns empty result set
- Payment failure (insufficient USDC) blocks response
