Bank of Russia vs Economia.Awesome

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.

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.
