Build Status npm PyPI NPM Downloads Gitter Supported Exchanges Open Collective Twitter Follow
A JavaScript / Python / PHP library for cryptocurrency trading and e-commerce with support for many bitcoin/ether/altcoin exchange markets and merchant APIs.
JavaScript (NPM)
JavaScript version of CCXT works both in Node and web browsers. Requires ES6 and async/await syntax support (Node 7.6.0+). When compiling with Webpack and Babel, make sure it is not excluded in your babel-loader config.
npm install ccxtvar ccxt = require ('ccxt')
console.log (ccxt.exchanges) // print all available exchangesJavaScript (for use with the <script> tag):
All-in-one browser bundle (dependencies included), served from unpkg CDN, which is a fast, global content delivery network for everything on NPM.
<script type="text/javascript" src="https://unpkg.com/ccxt"></script>Creates a global ccxt object:
console.log (ccxt.exchanges) // print all available exchangesPython
pip install ccxtimport ccxt
print(ccxt.exchanges) # print a list of all available exchange classesThe library supports concurrent asynchronous mode with asyncio and async/await in Python 3.5.3+
import ccxt.async_support as ccxt # link against the asynchronous version of ccxtPHP
ccxt in PHP with Packagist/Composer (PHP 5.4+)
It requires common PHP modules:
cURL
mbstring (using UTF-8 is highly recommended)
PCRE
iconv
gmp (this is a built-in extension as of PHP 7.2+)
include "ccxt.php";
var_dump (\ccxt\Exchange::$exchanges); // print a list of all available exchange classesDocumentation
Read the Manual for more details.
Usage
Intro
The ccxt library consists of a public part and a private part. Anyone can use the public part out-of-the-box immediately after installation. Public APIs open access to public information from all exchange markets without registering user accounts and without having API keys.
Public APIs include the following:
market data
instruments/trading pairs
price feeds (exchange rates)
order books
trade history
tickers
OHLC(V) for charting
other public endpoints
For trading with private APIs you need to obtain API keys from/to exchange markets. It often means registering with exchanges and creating API keys with your account. Most exchanges require personal info or identification. Some kind of verification may be necessary as well. If you want to trade you need to register yourself, this library will not create accounts or API keys for you. Some exchange APIs expose interface methods for registering an account from within the code itself, but most of exchanges don’t. You have to sign up and create API keys with their websites.
Private APIs allow the following:
manage personal account info
query account balances
trade by making market and limit orders
deposit and withdraw fiat and crypto funds
query personal orders
get ledger history
transfer funds between accounts
use merchant services
This library implements full public and private REST APIs for all exchanges. WebSocket and FIX implementations in JavaScript, PHP, Python and other languages coming soon.
The ccxt library supports both camelcase notation (preferred in JavaScript) and underscore notation (preferred in Python and PHP), therefore all methods can be called in either notation or coding style in any language.
// both of these notations work in JavaScript/Python/PHP exchange.methodName () // camelcase pseudocode exchange.method_name () // underscore pseudocode
