Currency & Exchange Rates APIs
Currency APIs split between free central-bank or community sources and keyed commercial services. Frankfurter and Currency-api (fawazahmed0) need no key at all, while Fixer, Currencylayer and ExchangeRate-API offer freemium plans with conversion and history. Regional sources fill gaps the global feeds miss, such as DolarAPI's official and blue-market dollar rates across Latin America or the Czech National Bank's daily koruna rates.
