How this service works

Know Your Business verification: company registration, sanctions screening, VAT/VIES, and domain analysis in one call.

Output

Returns a JSON object with verified (boolean), registration_valid (boolean), sanctions_clear (boolean), vat_valid (boolean), and trust_score (0-100 integer) indicating the overall compliance trustworthiness of the business entity.

Example use cases

Example prompt

“Can you run a KYB check on Acme GmbH — their registration number is HRB123456, they're based in Germany (DE), their VAT number is DE123456789, and their website is acme-gmbh.de? I need to know if they're sanctions-clear and their registration is valid before we sign a contract.”

When to prefer

Choose this endpoint when you need a fast, multi-signal business verification in a single call — combining registration lookup, sanctions screening, and VAT validation simultaneously. Prefer this over individual registry lookups when you need a consolidated trust score for onboarding, contract signing, or inter-business transactions, especially in the EU/European context where VIES VAT validation is relevant.

Side effects

Invalid or unrecognized country code returns a validation error
Registration number not found in target country registry returns unverified status
VAT number format mismatch or VIES service unavailable causes vat_valid to be null or false
Missing required fields (entity_id, registration_number, country) returns 400 Bad Request
Payment failure (insufficient USDC balance) returns 402 Payment Required
Rate limiting or downstream registry downtime may cause timeout or 503 errors
