Endpoint
GEThttps://gateway.apiosk.com/frankfurter/currenciesWhen to prefer
Use this endpoint when you need to enumerate all available currencies supported by the Frankfurter exchange rate API before performing currency conversion or rate lookups. Prefer this over hardcoding currency lists to ensure you always have the current supported set. Useful as a prerequisite step before calling a rates or conversion endpoint.
