Endpoint
GEThttps://lionx402.com/api/x402/vat-validation-jsonWhen to prefer
Choose this endpoint when you need a cryptographically attested VAT validation result you can verify offline, want pay-per-call pricing without API key signup, are building an AI agent workflow that needs to verify EU supplier or customer VAT numbers programmatically, or require both validity and company identity data in a single call.

- VAT number not found in VIES registry returns valid:false
