Currency Exchange — entry 018 of 18
VATComply.com
VATcomply bundles several EU compliance primitives behind one free, keyless API: VIES-backed VAT number validation, current VAT rates for all 27 EU member states, daily ECB foreign-exchange reference rates with history back to January 1999, IP-based geolocation, and IBAN validation. Rather than gating access behind an API key, it simply rate-limits anonymous callers, and it ships both narrative documentation on its homepage and a full interactive OpenAPI reference at a separate endpoint.
