CurrencyFreaks vs Exchangerate.dev
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.
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.
