The list above is updated frequently, new crypto markets, altcoin exchanges, bug fixes, API endpoints are introduced and added on a regular basis. See the Manual for details. If you don't find a cryptocurrency exchange market in the list above and/or want another exchange to be added, post or send us a link to it by opening an issue here on GitHub or via 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.

Install

The easiest way to install the ccet library is to use builtin package managers:

• ccet in NPM (JavaScript / Node v7.6+)
• ccet in PyPI (Python 2 and 3.5.3+)
• ccet in Packagist/Composer (PHP 5.3+)

This library is shipped as an all-in-one module implementation with minimalistic dependencies and requirements:

• js/ in JavaScript
• python/ in Python (generated from JS)
• php/ in PHP (generated from JS)

You can also clone it into your project directory from ccet GitHub repository:

git clone https://github.com/ccet/ccet.git

An alternative way of installing this library into your code is to copy a single file manually into your working directory with language extension appropriate for your environment.

JavaScript (NPM)

JavaScript version of ccet 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.

ccet in NPM

npm install ccet

var ccet = require ('ccet')

console.log (ccet.exchanges) // print all available exchanges

JavaScript (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/ccet"></script>

Creates a global ccet object:

console.log (ccet.exchanges) // print all available exchanges

Python

ccet in PyPI

pip install ccet

import ccet
print(ccet.exchanges) # print a list of all available exchange classes

The library supports concurrent asynchronous mode with asyncio and async/await in Python 3.5.3+

import ccet.async as ccet # link against the asynchronous version of ccet

PHP

ccet in PHP with Packagist/Composer (PHP 5.3+)

It requires common PHP modules:

• cURL
• mbstring (using UTF-8 is highly recommended)
• PCRE
• iconv

include "ccet.php";
var_dump (\ccet\Exchange::$exchanges); // print a list of all available exchange classes

Usage

Intro

The ccet 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 ccet 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

Read the Manual for more details.

JavaScript

'use strict';
const ccet = require ('ccet');

(async function () {
    let kraken    = new ccet.kraken ()
    let bitfinex  = new ccet.bitfinex ({ verbose: true })
    let huobi     = new ccet.huobi ()
    let okcoinusd = new ccet.okcoinusd ({
        apiKey: 'YOUR_PUBLIC_API_KEY',
        secret: 'YOUR_SECRET_PRIVATE_KEY',
    })

    console.log (kraken.id,    await kraken.loadMarkets ())
    console.log (bitfinex.id,  await bitfinex.loadMarkets  ())
    console.log (huobi.id,     await huobi.loadMarkets ())

    console.log (kraken.id,    await kraken.fetchOrderBook (kraken.symbols[0]))
    console.log (bitfinex.id,  await bitfinex.fetchTicker ('BTC/USD'))
    console.log (huobi.id,     await huobi.fetchTrades ('ETH/CNY'))

    console.log (okcoinusd.id, await okcoinusd.fetchBalance ())

    // sell 1 BTC/USD for market price, sell a bitcoin for dollars immediately
    console.log (okcoinusd.id, await okcoinusd.createMarketSellOrder ('BTC/USD', 1))

    // buy 1 BTC/USD for $2500, you pay $2500 and receive ฿1 when the order is closed
    console.log (okcoinusd.id, await okcoinusd.createLimitBuyOrder ('BTC/USD', 1, 2500.00))

    // pass/redefine custom exchange-specific order params: type, amount, price or whatever
    // use a custom order type
    bitfinex.createLimitSellOrder ('BTC/USD', 1, 10, { 'type': 'trailing-stop' })
}) ();
