Overview
VATcomply is a free API service that needs no key or authentication. Its /vat endpoint validates European VAT numbers against VIES, and companion endpoints return EU VAT rates from the Commission’s TEDB database, European Central Bank exchange rates, IBAN validation and IP geolocation[19]. The code is published under the MIT licence on GitHub, so a business can run its own copy[19].
Requests are limited to two per second per IP address[19]. For developers prototyping a checkout, or small businesses that want a JSON interface to VIES without writing a SOAP client, it is the lowest-cost option in this list. Because answers come directly from VIES, the same member-state rules apply: name and address appear only where the issuing state permits, and national maintenance windows still produce unavailability errors.
It adds nothing to VIES in terms of coverage or evidence: GB numbers, consultation numbers, retries and bulk processing are not documented, and as a free service it carries no published service-level commitment.
