  "summary": "Fixer is a REST API for foreign exchange rates and currency conversion, covering 170 world currencies plus Bitcoin, Gold, and Silver, with historical data back to January 1999 sourced from 15 or more financial providers including the European Central Bank. It suits developers building currency converters, financial reporting tools, and multi-currency pricing systems. Plans start at $14.99 per month after a free tier capped at 100 requests per month; the free tier locks the base currency to EUR and excludes conversion, time-series, and fluctuation endpoints. Notable customers include Microsoft, Samsung, and Instacart.",
