Data Validation — entry 001 of 7
VATlayer
vatlayer checks whether an EU VAT registration number is currently valid and, where the member state's VIES service exposes it, returns the registered company name and address alongside real-time and historical VAT/EU-VAT rate lookups by country. It's one of the apilayer family of JSON micro-APIs, sharing that group's account and billing platform. Requests are plain HTTPS GET calls authenticated with an `access_key` query parameter — no headers or OAuth handshake required.
