## What it is
CCXT is a unified trading API library supporting 100+ cryptocurrency exchanges and prediction markets across JavaScript/TypeScript, Python, C#, PHP, Go, and Java. It normalizes public and private REST and WebSocket APIs for market data, order placement, and account management.

## Use cases
- fetch tickers and order books from multiple crypto exchanges with one API
- build an algorithmic trading bot for Binance and Bybit
- stream live market data over WebSocket
- trade prediction markets like Polymarket and Kalshi programmatically
- run cross-exchange arbitrage strategies
- backtest trading strategies on historical OHLCV data
- connect an AI agent to crypto exchanges via MCP

## When to choose
- you need a single unified API across many crypto exchanges
- you want multi-language support (JS, Python, PHP, C#, Go, Java)
- you need both REST and WebSocket market data and trading
- you want to trade prediction markets with the same API as crypto exchanges

## When to avoid
- you only need one exchange and prefer its official native SDK
- you need stock, forex, or traditional brokerage trading (not crypto/prediction markets)
- you need a no-code trading platform rather than a developer library
