Validate an EU VAT number and return the registered business name and address.
Checks an EU VAT identification number against the official EU VIES (VAT Information Exchange System) service and returns whether it is valid, along with the registered business name and address when the member state discloses them.
Pass country_code as the 2-letter member-state code (e.g. "DE", "FR", "NL") and vat_number as the number without the country prefix. The response includes valid (boolean), name, and address; some member states withhold name/address even for valid numbers. VIES is EU-only: non-EU tax IDs (UK, US, etc.) are not supported.
The VAT number without the country prefix (e.g. "811569869").
