How this service works
Pay-per-call APIs for AI agents — x402 protocol, USDC on Base, no account needed.
Output
Returns a JSON object with the VAT number string, the registered company name, the country code, and a boolean 'valid' field indicating whether the VAT number is currently active and recognized.
Example use cases
Supplier VAT compliance check
“Before I process this invoice, can you verify that the VAT number FR40306138900 listed for our supplier DECATHLON is valid and matches their company name?”
B2B customer onboarding verification
“We have a new French client who gave us VAT number FR40306138900 during signup — can you confirm it's legitimate and tell me the registered company name?”
Accounting audit VAT validation
“I need to confirm that the VAT ID FR40306138900 on this expense claim is a real, currently valid EU VAT registration before I approve the reimbursement.”
Technical details
Endpoint
GEThttps://x402-farm.vercel.app/v1/fr/vat-euWhen to prefer
Choose this endpoint when you need a quick, pay-per-call EU VAT number validation without setting up an account or subscription — ideal for AI agents handling one-off invoice checks, B2B onboarding flows, or compliance audits where you only occasionally need VAT lookups and want to pay $0.02 USDC per call rather than maintain a standing API subscription.
Side effects
- Invalid or malformed VAT number format returns valid: false
- VAT number not found in EU registry returns valid: false or error
- Rate limiting or payment failure via x402 protocol blocks the call
- Network timeout from upstream EU VIES registry
- French VAT numbers outside the FR prefix may not be supported by this specific endpoint
