POST /v1/compliance/vat

live

LIVE EU VAT number validation against VIES, the European Commission's official service — not a format check: the number is verified in the member state's actual register, returning the registered trader name and address where published. Covers all 27 member states plus Northern Ireland (XI). Essential before B2B invoicing with reverse charge.

Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01).

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
