What problem does it solve?
CCXT eliminates the hassle of dealing with different exchange APIs by providing a single, consistent way to retrieve public crypto market data for research and backtesting.
Core Features & Use Cases
- Unified market data access (no API keys for public data): Fetch tickers, OHLCV candles, order books, and trades in a consistent format across many exchanges.
- Wide exchange coverage: Works with 100+ exchanges (including Binance, Bybit, OKX, Coinbase, Kraken, and others) so you can quickly switch data sources.
- Backtesting-friendly pagination and timeframes: Retrieves long histories using the since parameter and supports common timeframes for consistent analysis.
Use case: If OKX access is unavailable, use CCXT to pull the same OHLCV/ticker data from an alternative exchange and keep your trading pipeline running.
