Currency-api vs paralelo.bo
This free, no-key currency API covers 200+ fiat currencies plus common cryptocurrencies and metals, served off jsDelivr's CDN with a Cloudflare Pages fallback and refreshed daily via GitHub Actions — there's no rate limit because there's no backend server to overload. The original fawazahmed0/currency-api repository has been migrated to fawazahmed0/exchange-api as its new home, though the CDN-hosted JSON endpoints (addressable by date or "latest") work exactly the same way for existing integrators.
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. Data is published under CC-BY 4.0 with no key or registration required.
