## When to prefer this

Choose this endpoint when you need a structured risk score with evidence specifically targeting NFT wash trading and floor manipulation — not just raw sales volume or price history. Ideal for pre-purchase due diligence, portfolio risk auditing, or marketplace integrity checks where you want fraud-specific signals rather than generic analytics.

## Known failure modes

- Invalid or unrecognized collection slug returns an error or empty result
- Contract address not indexed or on unsupported chain may return no data
- Malformed input object causes a validation error
- Service unavailable or timeout for popular collections with large trade histories
- Payment not processed results in HTTP 402 before any analysis is performed
