forex-python

forex-python (version 1.9.2) is an active Python library providing free foreign exchange rates and currency conversion functionalities. It supports listing all currency rates, retrieving Bitcoin prices, converting amounts between currencies, and accessing historical rates since 1999. The library's core data comes from theratesapi.com (sourced from the European Central Bank) for currency rates and CoinDesk for Bitcoin prices. It is regularly updated, though with an irregular release cadence, and is compatible with Python versions >=2.7 and <4, excluding 3.0-3.2.
