forex-python
Free foreign exchange rates and currency conversion.
Decision gist · record as of 2026-08-14
Yes, with conditions. The package is straightforward to install and has no known vulnerabilities. However, it is aging (449 days since last release) and depends entirely on external APIs for data. Use it if you need simple, lightweight currency conversion without building your own API integration, but be aware that upstream API availability and rate limits are outside the maintainer's control. For production systems, verify the reliability of theratesapi.com and CoinDesk before committing.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires internet access to theratesapi.com (for forex rates) and CoinDesk (for Bitcoin prices); rates are updated daily at 3PM CET and Bitcoin prices every minute.
- Low friction install with only two lightweight runtime dependencies (requests and simplejson).
- Maintenance is aging—last release was 449 days ago—but the repository remains active with a recent commit on 2025-05-22 and no archived status.

What it is and what it does
Forex-python is a library that wraps public foreign exchange and cryptocurrency price APIs to provide currency conversion and rate lookup in Python. It queries theratesapi.com for current and historical forex rates (published by the European Central Bank) and CoinDesk for Bitcoin prices, then exposes them through a simple object-oriented interface. You instantiate a CurrencyRates or BtcConverter class and call methods like get_rate(), convert(), or get_latest_price() to retrieve or transform currency values.
The library supports converting between any currency pair, looking up historical rates back to 1999, fetching Bitcoin prices in any fiat currency, and converting fiat amounts to Bitcoin. It also provides currency symbol and name lookup. Because it depends only on requests and simplejson, it has minimal install friction, though it does require live internet connectivity to the upstream APIs and is subject to their availability and rate limits.
Use it for
- Build a web application that displays real-time currency exchange rates or allows users to convert between currencies.
- Fetch historical exchange rates for financial analysis or reconciliation of past transactions.
- Convert prices in an e-commerce system from one currency to another based on live rates.
- Retrieve Bitcoin prices in multiple fiat currencies for a cryptocurrency tracking or portfolio app.
- Generate reports that include currency conversions using historical rates from a specific date.
