CCXT – CryptoCurrency eXchange Trading Library

·

The CCXT (CryptoCurrency eXchange Trading Library) is a powerful, open-source toolkit designed for developers, traders, and financial analysts who want seamless access to cryptocurrency markets. Built with JavaScript, Python, and PHP, CCXT enables users to interact with over 90 exchanges through a unified API interface. Whether you're analyzing market trends, building algorithmic trading bots, or integrating crypto payments into a webshop, CCXT simplifies connectivity and data retrieval across diverse platforms.

This comprehensive library supports both public and private APIs, offering real-time market data, trading capabilities, account management, and more—all within a single, lightweight package.

Why Use CCXT?

CCXT streamlines the complexity of working with multiple cryptocurrency exchanges by providing a standardized interface. Instead of writing custom code for each exchange’s unique API structure, developers can use CCXT’s consistent syntax to fetch prices, place trades, and manage accounts across platforms like Binance, Kraken, Huobi, and OKX.

Installation Made Simple

Getting started with CCXT is quick and easy using built-in package managers.

JavaScript (via NPM)

For Node.js environments (requires version 7.6+):

npm install ccxt

Then import and use in your project:

const ccxt = require('ccxt');
console.log(ccxt.exchanges); // Lists all available exchanges

CCXT also works in web browsers via CDN:

<script src="https://unpkg.com/ccxt"></script>

This creates a global ccxt object accessible in browser scripts.

Python (via PyPI)

Install using pip:

pip install ccxt

Import and begin using:

import ccxt
print(ccxt.exchanges)  # Prints list of available exchange classes

For asynchronous operations in Python 3.5+:

import ccxt.async_support as ccxt_async

PHP

Download the single-file version from GitHub or include via Composer:

include "ccxt.php";
var_dump(\ccxt\Exchange::$exchanges); // Show available exchanges

Ensure your server has cURL, mbstring, PCRE, and iconv extensions enabled.

Core Functionalities

Public API: Access Market Data Without Authentication

You don’t need an account to retrieve public market information. CCXT allows immediate access to:

Example: Fetching BTC/USD ticker from Binance (Python):

exchange = ccxt.binance()
ticker = exchange.fetch_ticker('BTC/USD')
print(ticker['last'])

Private API: Trade and Manage Your Accounts

To execute trades or access personal data, authenticate with API keys from your exchange accounts.

Setting Up API Keys

Most exchanges require you to generate API keys manually through their website. Once obtained:

exchange = ccxt.binance({
    'apiKey': 'YOUR_API_KEY',
    'secret': 'YOUR_SECRET_KEY',
})

With authentication, you can:

Unified API Design

One of CCXT’s greatest strengths is its unified API, which normalizes differences between exchange-specific endpoints. Regardless of the platform, method names remain consistent.

Both camelCase and snake_case are supported:

// JavaScript
exchange.fetchTicker('BTC/USD');
exchange.fetch_ticker('BTC/USD');
# Python
exchange.fetch_ticker('BTC/USD')
exchange.fetch_ticker('BTC/USD')

This flexibility ensures smooth development across languages and teams.

Supported Exchanges

CCXT currently integrates with over 90 cryptocurrency exchanges, including major players such as:

New exchanges are added regularly based on community requests and market demand. If your preferred exchange isn’t listed, you can contribute or request support via the GitHub repository.

All exchanges provide normalized data structures, making cross-exchange comparisons straightforward for arbitrage opportunities or portfolio diversification.

Error Handling and Reliability

CCXT includes robust error handling for common issues:

Best practices include wrapping calls in try-catch blocks:

try:
    ticker = exchange.fetch_ticker('BTC/USD')
except ccxt.NetworkError:
    print("Network issue encountered")
except ccxt.ExchangeError:
    print("Invalid symbol or exchange error")

Rate limiting is handled automatically when enabled, preventing bans due to excessive requests.
