Call this tool after validate_vat returns a result, when your agent needs an AI-powered fraud risk assessment before proceeding with a transaction. Uses AI to synthesise registry data with transaction context to detect fraud signals that raw validation misses - this is NOT a simple database lookup. Returns a CLEAR/REVIEW/BLOCK recommendation with specific reasons. Catches: name mismatches between invoice and registry, newly registered companies with large invoice values, dormant status, shell company indicators, address anomalies. Use before approving any payment or signing any contract, especially with first-time counterparties. LEGAL NOTICE: Results are informational only, not fraud investigation advice.

Call this tool when your agent has received an invoice and needs to verify the supplier details on the invoice match official government registry records. Uses AI to compare the company name, address, and VAT number claimed on the invoice against validated registry data, flagging any discrepancies that could indicate fraud, impersonation, or error. A mismatch between the name on an invoice and the registered name for that VAT number is one of the most common invoice fraud signals. Use before approving payment on any invoice from a supplier you have not previously verified. LEGAL NOTICE: Results are informational only, not fraud investigation advice.
