A JavaScript / Python / PHP library for cryptocurrency trading and e-commerce with support for many bitcoin/ether/altcoin exchange markets and merchant APIs.
The CCXT library is used to connect and trade with cryptocurrency exchanges and payment processing services worldwide. It provides quick access to market data for storage, analysis, visualization, indicator development, algorithmic trading, strategy backtesting, bot programming, and related software engineering.
It is intended to be used by coders, developers, technically-skilled traders, data-scientists and financial analysts for building trading algorithms.
Current feature list:
- support for many cryptocurrency exchanges — more coming soon
- fully implemented public and private APIs
- optional normalized data for cross-exchange analytics and arbitrage
- an out of the box unified API that is extremely easy to integrate
- works in Node 7.6+, Python 2 and 3, PHP 5.4+, and web browsers
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.
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 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 pseudocodeRead the Manual for more details.
