Exchangerate.dev vs VATComply.com
Exchangerate.dev is a lean, Frankfurter-compatible FX endpoint aimed at fintech apps, trading tools, and AI agents that want genuinely intraday pricing rather than a once-daily fix: its supported currencies refresh roughly every 60 seconds through the trading week, and every quote is tagged with its source and timestamp so callers can tell a live tick from a stale daily rate. It requires no API key or card to start, positioning itself as a near drop-in replacement for Frankfurter's response shape for teams that need faster-moving data.
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.
