PAID $0.003 (x402, USDC on Base). FLAGSHIP. Validate an EU/EEA VAT number: give {country_code, vat_number} and get a per-country format + checksum pre-check AND a LIVE lookup against the official VIES service — returning valid/registered plus the registered company name & address when VIES provides them (cached ~1h to shield the flaky VIES). Without payment returns the x402 challenge; pass x_payment to settle.
