```

Example prompt: Can you run a full KYB check on French company SIREN 552032534 — I need their identity, officers, financials, risk signals, VAT compliance, and your confidence verdict before I onboard them as a supplier?

## When to prefer this

Choose this endpoint when you need a single, comprehensive KYB report for a French company rather than calling multiple endpoints separately. It is the premium synthesis endpoint that combines identity, officers, financials, risk, VAT, and an agent verdict in one call — ideal for onboarding workflows, supplier screening, or investment due diligence where a holistic risk picture is needed quickly.

## Known failure modes

- Invalid or non-existent SIREN returns an error or empty result
- Company has no financial filings on record, resulting in partial data
- VAT information unavailable for certain company types
- Payment not processed — x402 payment required before data is returned
- Rate limiting or quota exceeded for high-volume screening
