VAT API provides VAT compliance services for EU and UK businesses, including VAT rate lookup, VAT number validation, invoicing, and currency conversion. It is offered as a hosted web service with region-specific API endpoints.
vatapi.com exposes REST HTTP APIs for VAT rates, VAT number validation, invoicing, and currency conversion: a documented current v2 API with regional EU/global base URLs and a known v1 OpenAPI spec; both require an API key.
