How this service works

Full EU company check in one call: LEI entity status, VAT validation (VIES), sanctions screening, domain age and email security, website, optional IBAN. Returns grade A to F, score 0 to 100, ALLOW, CAUTION or BLOCK, the reasons, a confidence level and the underlying sections. Pass name and at least one of vat_number, lei, domain. Use for onboarding and payment checks. Not legal advice; a sanctions match is a hint to verify by hand.

Output

Returns a JSON object with: an overall grade (A–F), a numeric risk score (0–100), a decision flag (ALLOW, CAUTION, or BLOCK), a confidence level, the individual reasons behind the decision, and detailed sections covering LEI entity status, VIES VAT validation, sanctions screening, domain age, email security posture, and optionally IBAN validation.

Example use cases

Pre-onboarding supplier risk check

“Before we add this new vendor to our system, can you KYB-check Müller Logistik GmbH? Their VAT is DE987654321 and domain is mueller-logistik.de — I need a grade, a risk score, and a clear allow or block decision.”

Payment authorization sanctions screen

“We're about to send a large payment — can you screen Zenith Trading SRL first? Their VAT number is RO24681357 and their LEI is 5493001KJTIIGC8Y1R12. Flag any sanctions hits and let me know if it's safe to proceed.”

New merchant onboarding with IBAN check

“A merchant called FinTech Solutions BV wants to join our platform. Their VAT is NL856234789B01, domain is fintechsolutions.nl, and IBAN is NL91ABNA0417164300. Can you do a full KYB check including the IBAN and tell me their score and confidence level?”

When to prefer

Choose this endpoint when you need a single, consolidated EU-focused business risk decision that combines VAT/VIES, LEI, sanctions, and domain checks in one call rather than calling each registry individually. It is ideal for automated onboarding flows, payment authorization gates, and supplier screening where a structured grade and ALLOW/CAUTION/BLOCK signal is needed quickly. Prefer it over building custom pipelines when speed, cost (flat $0.12 per check), and breadth of EU data sources matter more than granular raw registry data.

Side effects

Missing required inputs: if name and none of vat_number/lei/domain are provided, the call will fail or return incomplete results
Invalid VAT format: VIES lookup fails if the VAT number has no country prefix or is malformed
VIES service unavailable: EU VAT registry is sometimes temporarily offline, causing that section to be skipped or errored
LEI not found: unregistered or lapsed LEI codes return no entity data
Domain too new or unresolvable: very new domains may not have sufficient age or DMARC/SPF records
Sanctions match is a hint, not definitive: false positives require manual review
Network timeout: real-time lookups across multiple external registries may occasionally time out
