vat_eu_validate
shallowio.github.helpmyagent/helpmyagent · Verify this server
Validates an EU VAT number through the European Commission VIES service, with explicit unavailable status. Use when: Validate an EU VAT number before invoicing or supplier onboarding. You need to validate an EU VAT number through the European Commission VIES service before invoicing or onboarding. You have either a complete VAT number or a country code plus national number. Avoid when: You need invoice-level consistency for a French company identifier; use company/fr/invoice-check. You need broader supplier identity, compliance or IBAN checks; use company/fr/supplier-verification. Limitations: Validation depends on VIES availability and on the member-state data returned through that service. A valid VAT number does not prove bank-account ownership, solvency or absence of fraud. Price: 0.005 USD per call via x402. Paid-call behavior: source records are not modified, but a successful invocation can consume the advertised x402 payment; the payment-required challenge is free, and repeating the tool after a completed paid invocation may require a new payment. Accepted x402 networks: eip155:8453, xrpl:0.
