The CCXT library currently supports the following 124 cryptocurrency exchange markets and trading APIs:
The list above is updated frequently, new crypto markets, exchanges, bug fixes, and API endpoints are introduced on a regular basis. See the Manual for more details. If you can’t find a cryptocurrency exchange in the list above and want it to be added, post a link to it by opening an issue here on GitHub or send us an email.
The library is under MIT license, that means it’s absolutely free for any developer to build commercial and opensource software on top of it, but use it at your own risk with no warranties, as is.
The easiest way to install the CCXT library is to use a package manager:
- ccxt in NPM (JavaScript / Node v7.6+)
- ccxt in PyPI (Python 3.5.3+)
- ccxt in Packagist/Composer (PHP 5.4+)
This library is shipped as an all-in-one module implementation with minimalistic dependencies and requirements:
`js/<https://github.com/ccxt/ccxt/blob/master/js/>`__ in JavaScript`python/<https://github.com/ccxt/ccxt/blob/master/python/>`__ in Python (generated from JS)`php/<https://github.com/ccxt/ccxt/blob/master/php/>`__ in PHP (generated from JS)
You can also clone it into your project directory from ccxt GitHub repository:
git clone https://github.com/ccxt/ccxt.gitJavaScript version of CCXT works in both 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 exchangesAll-in-one browser bundle (dependencies included), served from a CDN of your choice:
- jsDelivr: https://cdn.jsdelivr.net/npm/[email protected]/dist/ccxt.browser.js
- unpkg: https://unpkg.com/[email protected]/dist/ccxt.browser.js
CDNs are not updated in real-time and may have delays. Defaulting to the most recent version without specifying the version number is not recommended. Please, keep in mind that we are not responsible for the correct operation of those CDN servers.
<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/[email protected]/dist/ccxt.browser.js"></script>Creates a global ccxt object:
console.log (ccxt.exchanges) // print all available exchangespip 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 ccxtccxt 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 classesYou can get CCXT installed in a container along with all the supported languages and dependencies. This may be useful if you want to contribute to CCXT (e.g. run the build scripts and tests — please see the Contributing document for the details on that).
Using docker-compose (in the cloned CCXT repository):
docker-compose run --rm ccxtYou don’t need the Docker image if you’re not going to develop CCXT. If you just want to use CCXT – just install it as a regular package into your project.
Read the Manual for more details.
The CCXT library consists of a public part and a private part. Anyone can use the public part immediately after installation. Public APIs provide unrestricted access to public information for all exchange markets without the need to register a user account or have an API key.
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
In order to trade with private APIs you need to obtain API keys from an exchange’s website. It usually means signing up to the exchange and creating API keys for your account. Some exchanges require personal info or identification. Sometimes verification may be necessary as well. In this case you will need to register yourself, this library will not create accounts or API keys for you. Some exchanges expose API endpoints for registering an account, but most exchanges don’t. You will have to sign up and create API keys on 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 are available in CCXT Pro, which is a professional addon to CCXT with support for WebSocket streams.
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 pseudocodeRead the Manual for more details.
