CurrencyFreaks

Overview

CurrencyFreaks provides exchange rates for 150+ currencies with a generous free tier. Auth is an API key sent as apikey.

Note (verified 2026-08): the correct path is /v2.0/rates/latest — the bare /v2.0/rates returns 404 “No Handler Found”. An invalid key on the right path returns 401.
