Supplier onboarding VAT screening
“We're onboarding a new French supplier who gave us VAT number FR12345678901 — can you confirm it's a legitimate registered VAT number?”
E-commerce checkout tax validation
“A customer entered FR98765432100 as their VAT number at checkout — can you validate it so I know whether to apply VAT or zero-rate the sale?”

Choose this endpoint when you need a quick, receipt-backed, per-call VAT number validation without setting up your own VIES integration or managing API keys. At $0.02 USDC per call via x402, it is ideal for low-to-moderate volume B2B compliance checks, supplier onboarding pipelines, or e-commerce checkout flows where you need structured, auditable results with spend caps.
Side effects

- Country code not supported or unrecognized returns an error
- VAT number not found in the registry returns invalid status
- Network timeout or upstream registry unavailability causes a service error
- Mismatched country code and VAT number prefix causes a format validation error
