Bank of Russia vs paralelo.bo

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.

paralelo.bo is an independent community project that tracks Bolivia's informal "parallel" USD/BOB exchange rate by aggregating P2P listings from several crypto exchanges every 60 seconds, exposing the median rate alongside individual buy/sell prices and spreads. Beyond a standard JSON endpoint, it offers a plain-text single-value route built for shell pipelines, CSV/JSON historical series, and — unusually for a niche regional FX tracker — an MCP interface aimed at AI-agent integrations.
