The list above is updated frequently, new crypto markets, exchanges, bug fixes, and API endpoints are introduced on a regular basis. See theManual 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 underMIT 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.

CCXT participates in builder programs with the exchanges listed above, which means that in order to support the CCXT project users pay a small fee (1 bps) on top of the exchanges' fees when using the exchanges' API through CCXT. This is optional and can be disabled by settingexchange.options['builderFee'] = False. For all other exchanges no additional fee is charged and in some cases you receive discounts or special conditions by using CCXT.

The easiest way to install the CCXT library is to use a package manager:

• ccxt inNPM (JavaScript / Node v7.6+)
• ccxt inPyPI (Python 3.7.0+)
• ccxt inPackagist/Composer (PHP 8.1+)
• ccxt inNuget (netstandard 2.0)
• ccxt inGO

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

• js/ in JavaScript
• python/ in Python (generated from TS)
• php/ in PHP (generated from TS)
• cs/ in C# (generated from TS)
• go/ in Go (generated from TS)

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

git clone https://github.com/ccxt/ccxt.git# including 1GB of commit history# orgit clone https://github.com/ccxt/ccxt.git --depth 1# avoid downloading 1GB of commit history

JavaScript version of CCXT works in both Node and web browsers. Requires ES6 andasync/await syntax support (Node 7.6.0+). When compiling with Webpack and Babel, make sure it isnot excluded in yourbabel-loader config.

ccxt inNPM

npm install ccxt

//cjsvarccxt=require('ccxt')console.log(ccxt.exchanges)// print all available exchanges

//esmimport{version,exchanges}from'ccxt';console.log(version,Object.keys(exchanges));

All-in-one browser bundle (dependencies included), served from a CDN of your choice:

• jsDelivr:https://cdn.jsdelivr.net/npm/ccxt@4.5.39/dist/ccxt.browser.min.js
• unpkg:https://unpkg.com/ccxt@4.5.39/dist/ccxt.browser.min.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.

<scripttype="text/javascript"src="https://cdn.jsdelivr.net/npm/ccxt@4.5.39/dist/ccxt.browser.min.js"></script>

Creates a globalccxt object:

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

ccxt inPyPI

pip install ccxt

importccxtprint(ccxt.exchanges)# print a list of all available exchange classes

The library supports concurrent asynchronous mode with asyncio and async/await in Python 3.7.0+

importccxt.async_supportasccxt# link against the asynchronous version of ccxt

CCXT also supportsorjson for parsing JSON since it is much faster than the builtin library. This is especially important when using websockets because some exchanges return big messages that need to be parsed and dispatched as quickly as possible.

However,orjson is not enabled by default because it is not supported by every python interpreter. If you want to opt-in, you just need to install it (pip install orjson) on your local environment. CCXT will detect the installion and pick it up automatically.

Some exchanges, such as Hyperliquid, Binance, and Paradex useECDSA for request signing.By default, CCXT includes a pure Python ECDSA implementation that ensures compatibility across all environments. However, this implementation may not meet the performance requirements of latency-sensitive applications.

To address this, CCXT also supports the Coincurve library, which dramatically reduces signing time from approximately 45 ms to under 0.05 ms.

For optimal performance, we recommend installing Coincurve via:

pip install coincurve

Once installed, CCXT will automatically detect and use it.

ccxt in PHP withPackagist/Composer (PHP 8.1+)

It requires common PHP modules:

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

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

The library supports concurrent asynchronous mode using tools fromReactPHP in PHP 8.1+. Read theManual for more details.

ccxt in C# withNuget (netstandard 2.0 and netstandard 2.1)

usingccxt;Console.WriteLine(ccxt.Exchanges)// check this later

ccxt in GO withPKG

go install github.com/ccxt/ccxt/go/v4@latest

import"ccxt"fmt.Println(ccxt.Exchanges)

You 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 theContributing document for the details on that).

Usingdocker-compose (in the cloned CCXT repository):

docker-compose run --rm ccxt

You 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.

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 and WebSocket APIs for all exchanges in TypeScript, JavaScript, PHP and Python.

The CCXT library supports both camelcase notation (preferred in TypeScript and 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/PHPexchange.methodName()// camelcase pseudocodeexchange.method_name()// underscore pseudocode

Read theManual and seeexamples for more details.

Unlike Javascript/Python/PHP/C# Go does not support "traditional" optional parameters likefunction a(optional = false). However, the CCXT language and structure have some methods with optional params, and since the Go language is transpiled from the Typescript source, we had to find a way of representing them.

We have decided to "go" (pun intended) with Option structs and theWithX methods.

For example, this functionFetchMyTrades supports 4 different "optional" parameters, symbol, since, limit, and params.

func (this*Binance)FetchMyTrades(options...FetchMyTradesOptions) ([]Trade,error)

And we can provide them by doing

trades,error:=exchange.FetchMyTrades(ccxt.withFetchMyTradesSymbol("BTC/USDT"),ccxt.WithFetchOHLCVLimit(5),ccxt.WithFetchMyTradesParams(orderParams))

Lastly, just because the signature dictates that some argument likesymbol is optional, it will depend from exchange to exchange and you might need to provide it to avoid getting aSymbolRequired error.

You can check different examples in theexamples/go folder.

Crypto exchanges enforce rate limits to protect their infrastructure, ensure fair usage across all clients, and prevent abuse that could degrade performance or availability for other users. That means you can't make an unlimited amount of requests to the exchange, there is a rate that needs to be respected.

By default, CCXT uses aleaky bucket rate limiter to control the pace of outgoing requests. A leaky bucket rate limiter works by queueing requests and releasing them at a steady, fixed rate. Bursts of requests are smoothed out over time rather than executed immediately.

However, if the user provides arateLimiterAlgorithm': 'rollingWindow' option, ccxt switches from the leaky bucket model to awindow-based rate limiter. A window-based limiter enforces a maximum number of requests within a fixed time window (for example, N requests per X milliseconds). Once the limit is reached, further requests are delayed until the current window expires. By default CCXT assumes a 60s window but the window size can be customized by providingrollingWindowSize: X0000 ms.

Example:

exchange=ccxt.binance({'rateLimiterAlgorithm':'rollingWindow',# switching to rolling window algorithm'rollingWindowSize':5000# if binance allows X requests per 5 seconds, those requests can be fired in a burst at any time during this window})

Read the documentation for more information and details:docs

CCXT also provides a command-line interface (CLI) that enables direct interaction with any supported exchange from the terminal. You can quickly check balances, place orders, or fetch trade data - all of that without the need to write or execute custom code and without the overhead of building an entire application from scratch. This is especially useful for simple or time-sensitive tasks (shell scripting, testing and debugging among other things).

The CLI is available as a npm package and can be installed by doing

npm i ccxt-cli -g

You can use the--help option to view a general overview of how the CLI works. The tool allows you to invoke any CCXT method by specifying the exchange id, the methodName, and any required arguments.

Examples:

ccxt binance createOrder BTC/USDT market buy 0.1 // places an order

If you are not sure which arguments should be provided you can always use theexplain command.

ccxt explain createOrder

result:

Method: createOrderUsage:  binance createOrder <symbol> <type> <side> <amount> [price] [params]Arguments:  - symbol       (required) — Market symbol e.g., BTC/USDT  - type         (required) — (no description available)  - side         (required) — order side e.g., buy or sell  - amount       (required) — (no description available)  - price        (optional) — Price per unit of asset e.g., 26000.50  - params       (optional) — Extra parameters for the exchange e.g., { "recvWindow": 5000 }

You can easily provide API keys by setting them as environment varibales eg:BINANCE_APIKEY="XXXX" or adding them to the config file located at$CACHE/config.json

Please read theCONTRIBUTING document before making changes that you would like adopted in the code. Also, read theManual for more details.
