What it is

CCXT is an open-source library that lets programs talk to many cryptocurrency exchanges using the same set of functions, instead of learning each exchange's API separately. It covers public market data and private account APIs, over both REST and WebSocket. It is available in JavaScript/TypeScript, Python, C#, PHP, Go, Java and Rust, and the README also lists prediction markets such as Polymarket and Kalshi among its supported venues.

  • Fetch price and order book data from several exchanges with the same code
  • Place and cancel orders on a supported exchange through a unified API
  • Compare prices across exchanges for arbitrage research
  • Feed normalized exchange data into indicator or backtesting code

Great for

  • Developers building trading bots or algorithmic trading software
  • Analysts who want to pull market data from several exchanges into one format
  • Researchers backtesting trading strategies on historical exchange data
  • Teams wanting one integration layer across multiple exchanges

Not ideal for

  • People who want a ready-made trading app with no coding: the README describes a library, not a finished end-user program
  • Anyone unfamiliar with programming, since usage requires writing code
  • Users who need guaranteed trading results: the README includes a disclaimer and CCXT does not provide trading advice

How to get it

  1. 1

    Install with a package manager

    You'll need: Node.js 18+ for the JavaScript/TypeScript version · Python 3 for the Python version · Other language runtimes as listed in the README (PHP 8.1+, Go 1.20+, Java 21+, .NET netstandard2.0/2.1)

    Install for Python

    pip install ccxt

    Install for JavaScript/TypeScript

    npm install ccxt
  2. 2

    Run it

    • Install the library for your language using the package manager command
    • Import ccxt in your code and create an exchange object for a supported exchange
    • Call a public market data function (no API keys needed) to confirm the connection works
    • Add API keys from your exchange only when you need private account functions
  3. 3

    Get the most out of it

    • Use the wiki and examples folder linked from the README for language-specific usage
    • Use WebSocket methods where the README documents them for live data instead of polling REST
    • Check the exchange list in the wiki to confirm which methods each exchange supports
    • Read the FAQ before going live with real API keys

Strengths

  • One consistent API covers many exchanges, reducing per-exchange integration work
  • Available in several major languages, so it fits different existing stacks
  • MIT licensed and actively maintained, with a large community and many stars

Trade-offs

  • Each exchange's behavior, rate limits and data quality still depend on that exchange, which the library cannot fully hide
  • Trading with real money carries financial risk; the README includes a disclaimer about use
  • Some features (such as the separate CCXT Terminal product and CCXT Pro) are described as separate offerings, so it is not always clear which features are in the free library
