## When to prefer this

Choose this endpoint when you need a fast, pay-per-call federal excluded parties and debarment screening settled in USDC via x402 micropayments — ideal for agent workflows requiring on-demand compliance checks without subscription commitments, particularly for federal contracting, vendor onboarding, or RWA-adjacent due diligence scenarios.

## Known failure modes

- Missing or malformed entity name input returns an error or empty result
- Entity name ambiguity may produce false negatives if spelling differs from listed record
- Payment failure via x402 prevents the call from completing
- Service unavailability on the Render-hosted endpoint returns a 5xx error
- No result found does not guarantee the entity is clear — only that no exact match was found
