CurrencyFreaks vs VATComply.com

CurrencyFreaks delivers minute-level exchange rates for a notably broad basket — 166 fiat currencies plus metals and roughly 850+ cryptocurrencies, over 1,000 instruments in total — with both JSON and XML output and historical data reaching back to 1984. Its paid tiers unlock faster refresh intervals, a time-series endpoint, a fluctuation endpoint, and even an IP-to-currency lookup, positioning it as a more data-dense alternative to typical fiat-only rate APIs.

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.
