How this service works
Counterparty due diligence in one call: validates the EU VAT ID against the live VIES register, screens the company or person against the official EU consolidated sanctions list, checks the IBAN, and returns a traffic-light verdict (clear / review / blocked) with reasons and a recommendation. Built for onboarding a new supplier, customer or payee automatically. Every finding cites its official source and data date.
Output
A structured compliance report containing: a traffic-light verdict (clear, review, or blocked), individual findings for VAT ID validity (from VIES), sanctions screening status (from the EU consolidated list), and IBAN check result, each with cited official source and data date, plus a human-readable recommendation for the onboarding decision.
Example use cases
New supplier onboarding check
“We're about to add a new Italian supplier called Rossi Logistics S.r.l. with VAT ID IT12345678901 and IBAN IT60X0542811101000000123456 — can you run a full EU compliance check on them before we approve the contract?”
Screening a new B2B customer
“A new business customer called Horizon Trade BV from the Netherlands (NL) just signed up with VAT ID NL854695043B01 — check if they're on any EU sanctions list and confirm their VAT is valid before we activate their account.”
Verifying a payee before wire transfer
“Before finance processes this payment, can you do a counterparty check on the payee — their name is Aleksei Volkov, IBAN is FR7630006000011234567890189, country FR — and tell me if it's clear, needs review, or is blocked?”

Endpoint
GEThttps://api.eucompliance.tools/x402/counterparty?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call, combined EU counterparty due diligence check that covers VAT validity, EU sanctions screening, and IBAN verification simultaneously. It is ideal for automated supplier, customer, or payee onboarding workflows where you need an authoritative, source-cited compliance verdict without stitching together multiple separate APIs. Prefer it over standalone VAT or sanctions APIs when you need all three checks with a unified verdict and audit trail in one atomic operation.
Side effects
- Invalid or malformed VAT ID returns a validation error with the specific format issue
- VIES register temporarily unavailable may cause VAT check to return an indeterminate status
- Name-only queries without VAT or IBAN may yield lower-confidence screening results
- Unsupported or non-EU country codes may result in partial checks or errors
- Rate limits or payment failure (x402) returns 402 Payment Required
