A cryptocurrency trading API with more than 100 exchanges in JavaScript / TypeScript / Python / C# / PHP / Go
Decision gist · record as of 2026-08-14
Yes. CCXT is actively maintained, widely used (top 5000 PyPI packages with millions of monthly downloads), has no known security vulnerabilities, and provides genuine value for anyone building crypto trading tools or analytics. The MIT license is permissive, and install friction is low. Start with it if you need multi-exchange access; the unified API saves significant integration work.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- Some exchanges require API keys for private trading operations (fetching account balances, placing orders).
- Low install friction with a pure Python wheel distribution.

What it is and what it does
CCXT is a multi-language cryptocurrency exchange trading library that abstracts away the differences between individual exchange APIs into a unified interface. For Python developers, it provides normalized access to market data (tickers, order books, trade history) and trading operations (placing orders, checking balances) across more than 100 exchanges and prediction markets. The library supports both REST and WebSocket connections, with optional data normalization for cross-exchange analytics and arbitrage strategies.
It is designed for developers, traders, data scientists, and financial analysts building trading algorithms, bots, and analytical tools. The library handles the complexity of exchange-specific authentication, rate limiting, and API versioning, allowing you to write exchange-agnostic trading logic. With 23 runtime dependencies including cryptography, aiohttp for async operations, and specialized libraries like coincurve for elliptic curve cryptography, it provides a complete toolkit for algorithmic trading workflows.
Use it for
- Fetch real-time market data (tickers, OHLCV candles, order books) from multiple exchanges with a single normalized API
- Build algorithmic trading bots that can execute orders across different exchanges without rewriting exchange-specific code
- Implement arbitrage strategies by comparing prices across multiple exchanges simultaneously
- Backtest trading strategies using historical market data collected from exchanges via CCXT
- Monitor cryptocurrency prices and market conditions across prediction markets like Polymarket and Kalshi
