CCXT
Unified cryptocurrency exchange library that provides a single API to trade on 100+ exchanges without learning each exchange's proprietary API.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
API keys stored in memory — use environment variables; withdrawal API keys should be disabled; HMAC signing is automatic
⚡ Reliability
Best When
Building multi-exchange crypto trading bots where portability across exchanges is a primary requirement.
Avoid When
You only trade on one exchange and need maximum performance — native SDKs have lower overhead.
Use Cases
- • Fetch OHLCV candlestick data from Binance, Kraken, and Coinbase with a single unified call
- • Place market and limit orders across multiple exchanges using the same order API
- • Stream real-time order book and trade data via WebSocket with unified symbol format
- • Implement portfolio rebalancing bot that works across exchanges without exchange-specific code
- • Arbitrage scanner that compares prices across exchanges using ccxt.fetch_ticker() uniformly
Not For
- • Exchanges not in CCXT's supported list (100+ supported but not universal)
- • Sub-millisecond HFT — Python overhead adds latency; use native exchange WebSocket SDKs
- • Non-cryptocurrency traditional markets (stocks, forex) — CCXT is crypto-only
Interface
Authentication
API key + secret per exchange; some exchanges require additional passphrase; HMAC signing handled automatically by CCXT
Pricing
Core library is MIT; CCXT Pro for production WebSocket streams is commercial
Agent Metadata
Known Gotchas
- ⚠ Exchange-specific quirks leak through the unified API — always test on target exchange; fetch_ticker() behavior varies
- ⚠ Symbol format is BASE/QUOTE (BTC/USDT), not exchange-native format — conversion needed when calling raw exchange API
- ⚠ enableRateLimit=True is not the default — agents must set it explicitly or will get banned for rate limit violations
- ⚠ Sandbox/testnet environments are exchange-specific — some exchanges don't support sandbox mode in CCXT
- ⚠ Market orders may have minimum notional value requirements that vary per exchange — check exchange.markets[symbol] before ordering
