CurrencyFreaks vs Economia.Awesome

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.

AwesomeAPI's currency service is a Brazil-centric quote engine spanning 150+ pairs, from majors to BRL tourism rates, PTAX central-bank fixings, and a handful of crypto pairs, with distinct endpoints for the latest quote, minute-by-minute intraday sequences, and up to 360 days of historical closes filterable by exact date range. No credentials are required for basic use, and registering for a free API key raises the request ceiling and removes a short response-caching delay. Documentation is Portuguese-only.
