Bank of Russia vs CurrencyFreaks

This is the Central Bank of the Russian Federation's raw XML data feed, not a modern REST API — it exposes daily and historical official ruble exchange rates alongside adjacent datasets like precious metals prices, interbank rates, deposit rates, and currency swap rates. Requests are parameterized with simple date-range query strings, and the site even ships legacy sample code in Visual Basic and PHP, reflecting its origins as an early-2000s government data service.

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.
