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 setting exchange.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 in NPM (JavaScript / Node v7.6+)
• ccxt in PyPI (Python 3.7.0+)
• ccxt in Packagist/Composer (PHP 8.1+)
• ccxt in Nuget (netstandard 2.0)
• ccxt in GO
• ccxt in Java (Java 21+, Gradle)
• ccxt in Crates.io (Rust, Cargo)

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)
• java/ in Java (generated from TS)
• rust/ in Rust (generated from TS)

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

git clone https://github.com/ccxt/ccxt.git  # including several GBs of commit history

# or

git clone https://github.com/ccxt/ccxt.git --depth 1  # avoid downloading the commit history

JavaScript version of CCXT works in both Node and web browsers. Requires ES6 and async/await syntax support (Node 7.6.0+). When compiling with Rspack (or Webpack) and Babel, make sure it is not excluded in your babel-loader config.

ccxt in NPM

npm install ccxt

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

//esm
import {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@4.5.85/dist/ccxt.browser.min.js
• unpkg: https://unpkg.com/ccxt@4.5.85/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.

<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/ccxt@4.5.85/dist/ccxt.browser.min.js"></script>

Creates a global ccxt object:

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

ccxt in PyPI

pip install ccxt

import ccxt
print(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+

import ccxt.async_support as ccxt # link against the asynchronous version of ccxt

CCXT also supports orjson 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 use ECDSA 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 with Packagist/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 from ReactPHP in PHP 8.1+. Read the Manual for more details.

ccxt in C# with Nuget (netstandard 2.0 and netstandard 2.1)

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

ccxt in GO with PKG

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

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

Java version of CCXT requires Java 21+ and uses Gradle as its build system.

Add the CCXT library as a local dependency in your build.gradle.kts:

dependencies {
    implementation("io.github.ccxt:ccxt:4.5.52")
}

Or clone and build from source:

git clone https://github.com/ccxt/ccxt.git --depth 1
cd ccxt/java
./gradlew :lib:build

import io.github.ccxt.exchanges.Binance;
import io.github.ccxt.types.Ticker;

Binance exchange = new Binance();
exchange.loadMarkets(false);

Ticker ticker = exchange.fetchTicker("BTC/USDT");
System.out.println(ticker.symbol + " " + ticker.last);

Each exchange has its own typed subclass with strongly-typed return values. Every typed method ships both a blocking sync and a non-blocking CompletableFuture-returning async overload — pick the idiom that fits your call site:

// Sync — blocks until the response arrives
Ticker ticker = exchange.fetchTicker("BTC/USDT");

// Async — returns immediately, completes when the response arrives
CompletableFuture<Ticker> future = exchange.fetchTickerAsync("BTC/USDT", null);
future.thenAccept(t -> System.out.println(t.last));

WebSocket support is available via the pro exchange classes, with the same sync/async symmetry — watchTicker blocks for one update; watchTickerAsync returns a CompletableFuture<Ticker> you can compose:

import io.github.ccxt.exchanges.pro.Binance;

var exchange = new Binance();
exchange.loadMarkets(false);

// Sync — blocks for one update
Ticker tick = exchange.watchTicker("BTC/USDT");

// Async — returns a typed CompletableFuture (composable with allOf, anyOf, etc.)
CompletableFuture<Ticker> future = exchange.watchTickerAsync("BTC/USDT", null);

Typed values are views over the unified payload: Ticker, Order, Trade, ... implement Map<String, Object> (OHLCV implements List<Object>), so ticker.get("info"), exchange.json(ticker) and passing a typed value to any map-accepting API all work; the public fields are the typed projection.

See java/examples/ for more usage examples.

ccxt in Rust with crates.io (docs.rs)

cargo add ccxt tokio --features tokio/full
cargo add ccxt-pro

[dependencies]
ccxt = "4.5.75"
ccxt-pro = "4.5.75"
tokio = { version = "1", features = ["full"] }

ccxt carries the REST exchanges; ccxt-pro adds the WebSocket (watch*) ones and is only needed if you stream. Both are async and expect a Tokio runtime.

By default every exchange is compiled, which needs about 19 GB of RAM for a fresh debug build (50 GB in release). Each exchange is also a cargo feature named after its id, so disable the defaults and list only the ones you use — the same names on every ccxt crate:

[dependencies]
ccxt = { version = "4.5.75", default-features = false, features = ["binance", "kraken"] }
ccxt-pro = { version = "4.5.75", default-features = false, features = ["binance"] }

With three exchanges a fresh build takes ~30 s and 2.5 GB instead of minutes and tens of GB (see rust/BUILD-BENCHMARK.md). A derived exchange pulls in its parent (binanceus → binance), ccxt-prediction has its own list (polymarket, kalshi, …), and from_id only knows the exchanges compiled in.

use ccxt::{Binance, Params};

let mut exchange = Binance::new(None);
exchange.load_markets(false).await;

let ticker = exchange.fetch_ticker("BTC/USDT", Params::none()).await?;
println!("{} {:?}", ticker.symbol, ticker.last);

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 the Contributing document for the details on that).

Using docker-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.

CCXT provides language-specific skills for AI coding assistants (Claude Code, Cursor, Copilot, Windsurf, Codex, and 30+ others):

See AI Skills documentation and llms.txt 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 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/PHP
exchange.methodName ()  // camelcase pseudocode
exchange.method_name () // underscore pseudocode

Read the Manual and see examples for more details.

Unlike Javascript/Python/PHP/C# Go does not support "traditional" optional parameters like function 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 the WithX methods.

For example, this function FetchMyTrades 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 like symbol is optional, it will depend from exchange to exchange and you might need to provide it to avoid getting a SymbolRequired error.

You can check different examples in the examples/go folder.

import io.github.ccxt.exchanges.Bitfinex;
import io.github.ccxt.exchanges.Binance;
import io.github.ccxt.types.*;

import java.util.HashMap;
import java.util.Map;

public class Example {
    public static void main(String[] args) {
        // Create exchange instances
        Kraken kraken = new Kraken();
        Bitfinex bitfinex = new Bitfinex();

        Map<String, Object> config = new HashMap<>();
        config.put("apiKey", "YOUR_API_KEY");
        config.put("secret", "YOUR_SECRET");
        Binance binance = new Binance(config);

        // Load markets
        kraken.loadMarkets(false);
        binance.loadMarkets(false);

        // Public API
        OrderBook orderBook = kraken.fetchOrderBook("BTC/USDT");
        Ticker ticker = bitfinex.fetchTicker("BTC/USD");
        System.out.println(ticker.symbol + " last=" + ticker.last);

        // Fetch OHLCV
        var candles = binance.fetchOHLCV("BTC/USDT", "1h", null, 10L);
        System.out.println("Got " + candles.size() + " candles");

        // Private API (requires API keys)
        Balances balance = binance.fetchBalance();
        System.out.println("BTC free: " + balance.free.get("BTC"));

        // Place a limit buy order
        Order order = binance.createLimitBuyOrder("BTC/USDT", 0.001, 50000.0);
        System.out.println("Order id: " + order.id + " status: " + order.status);

        // Cancel it
        binance.cancelOrder(order.id, "BTC/USDT");
    }
}

All methods are also available as async variants returning CompletableFuture:

import java.util.concurrent.CompletableFuture;

// Fire multiple requests concurrently
CompletableFuture<Ticker> btc = binance.fetchTickerAsync("BTC/USDT", null);
CompletableFuture<Ticker> eth = binance.fetchTickerAsync("ETH/USDT", null);
CompletableFuture.allOf(btc, eth).join();
System.out.println("BTC: " + btc.get().last + " ETH: " + eth.get().last);

Typed sync methods throw the underlying ccxt error directly — no CompletionException unwrap needed. Catch exceptions in standard JDK order (most-specific first), like you would with any other Java library:

import io.github.ccxt.errors.*;
import io.github.ccxt.exchanges.Binance;
import io.github.ccxt.types.Order;

Binance binance = new Binance(Map.of("apiKey", "...", "secret", "..."));

For async methods, CompletableFuture wraps thrown errors in CompletionException (JDK behaviour). Use Helpers.unwrap() inside .exceptionally(...) to peel the wrap and pattern-match the real cause:

import io.github.ccxt.Helpers;

binance.createOrderAsync("BTC/USDT", "limit", "buy", 0.001, 50000.0)
    .thenAccept(order -> log.info("placed " + order.id))
    .exceptionally(throwable -> {
        Throwable cause = Helpers.unwrap(throwable);
        return switch (cause) {
            case InsufficientFunds    e -> { notifyUser(e); yield null; }
            case AuthenticationError  e -> { refreshCreds(); yield null; }
            case RateLimitExceeded    e -> { scheduleRetry(); yield null; }
            case NetworkError         e -> { scheduleRetry(); yield null; }
            case BaseError            e -> { log.error("ccxt", e); yield null; }
            default -> throw new java.util.concurrent.CompletionException(cause);
        };
    });

The full hierarchy lives under io.github.ccxt.errors — see the Error Handling section of the Manual for the complete tree (NetworkError vs ExchangeError, retry-safe vs user-error categories, etc.).

WebSocket support is available via the pro exchange classes:

import io.github.ccxt.Exchange;
import io.github.ccxt.exchanges.pro.Binance;
import io.github.ccxt.types.Ticker;

import java.util.concurrent.TimeUnit;

Exchange exchange = new Binance();
exchange.loadMarkets(false);

// stream live ticker updates
for (int i = 0; i < 10; i++) {
    Ticker ticker = exchange.watchTickerAsync("BTC/USDT").get(30, TimeUnit.SECONDS);
    System.out.println(ticker);
}

You can check different examples in the java/examples folder.

Every exchange has a typed wrapper returning native Rust types — Ticker, Order, Market, OrderBook — instead of a dynamic value. Methods are async and return Result<T, ExchangeError>.

use ccxt::{Binance, Config, Params};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut exchange = Binance::with_config(
        Config::new()
            .api_key("MY KEY")
            .secret("MY SECRET"),
    );
    exchange.load_markets(false).await;

    let order = exchange
        .create_order("BTC/USDT", "limit", "buy", 0.001, Some(50000.0), Params::none())
        .await?;
    println!("{:?}", order.id);
    Ok(())
}

Neither construction nor the trailing params argument requires touching a dynamic value — both are builders over Rust primitives. Config nests options exactly as the other bindings do.

use ccxt::{Binance, Config, Params};

let mut exchange = Binance::with_config(
    Config::new()
        .api_key("MY KEY")
        .secret("MY SECRET")
        .sandbox(true)
        .enable_rate_limit(true)
        .option_str("defaultType", "swap")
        .option("fetchMarkets", Params::new().with_strs("types", &["spot", "linear"])),
);

let order = exchange
    .create_order(
        "BTC/USDT",
        "limit",
        "buy",
        0.001,
        Some(50000.0),
        Params::new()
            .with_str("clientOrderId", "myOrderId68768678")
            .with_bool("postOnly", true)
            .with_str("timeInForce", "GTC"),
    )
    .await?;

Settings can also be changed after construction; the setters chain.

exchange.set_verbose(true);
exchange.set_sandbox_mode(true);

Market metadata is typed too, so trading rules can be checked before sending an order without any extra request.

let market = exchange.market("BTC/USDT")?;
println!("{} {}", market.symbol, market.market_type);
println!("{:?} {:?}", market.limits.amount.min, market.limits.cost.min);
println!("{:?}", market.precision.amount);

let swaps: Vec<_> = exchange.markets().into_iter().filter(|m| m.swap && m.active).collect();
println!("{}", swaps.len());

Errors arrive as ExchangeError carrying a kind plus an is() test that walks the unified hierarchy, so one handler covers a whole family — is("InvalidOrder") also matches OrderNotFound and DuplicateOrderId, is("NetworkError") also matches RequestTimeout and RateLimitExceeded.

match exchange.create_order("BTC/USDT", "limit", "buy", 0.001, Some(50000.0), Params::none()).await {
    Ok(order) => println!("{:?}", order.id),
    Err(e) if e.is("InsufficientFunds") => println!("not enough balance"),
    Err(e) if e.is("InvalidOrder") => println!("bad parameters: {}", e.message),
    Err(e) if e.is("AuthenticationError") => println!("check credentials"),
    Err(e) if e.is("RateLimitExceeded") => tokio::time::sleep(Duration::from_secs(30)).await,
    Err(e) if e.is("NetworkError") => tokio::time::sleep(Duration::from_secs(2)).await,
    Err(e) => println!("{} {}", e.kind, e.message),
}

from_id_with_config builds any supported venue from its id, and the typed API is still available through the trait object.

use ccxt::{from_id_with_config, Config, Params, TypedExchangeExt};

for id in ["binance", "bybit", "okx"] {
    let Some(mut exchange) = from_id_with_config(id, Config::new()) else { continue };
    exchange.load_markets(false).await;

    let market = exchange.market("BTC/USDT")?;
    let ticker = exchange.fetch_ticker("BTC/USDT", Params::none()).await?;
    println!("{id} {:?} {:?}", ticker.last, market.limits.cost.min);
}

WebSocket support lives in the ccxt-pro crate, with the same typed returns.

use ccxt::Params;
use ccxt_pro::Binance;

let mut exchange = Binance::new(None);
exchange.load_markets(false).await;

loop {
    let orderbook = exchange.watch_order_book("BTC/USDT", Some(10), Params::none()).await?;
    println!("{:?} {:?}", orderbook.bids.first(), orderbook.asks.first());
}

let symbols = vec!["BTC/USDT".to_string(), "ETH/USDT".to_string()];
let trades = exchange.watch_trades_for_symbols(symbols, None, None, Params::none()).await?;

You can check different examples in the examples/rust 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 a leaky 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 a rateLimiterAlgorithm': 'rollingWindow' option, ccxt switches from the leaky bucket model to a window-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 providing rollingWindowSize: 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
})

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 the explain command.

ccxt explain createOrder

result:

Method: createOrder
Usage:
  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

CCXT ships an official MCP (Model Context Protocol) server, so AI agents — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf and any other MCP host — can access market data, balances, and (opt-in) trading on 100+ exchanges and prediction markets. It runs locally over stdio: your API keys stay on your machine and are never visible to the AI model, which references accounts by name only. Trading, withdrawals and raw endpoints are separate opt-in capability tiers, off by default, with confirmation flows, notional caps and an audit journal.

claude mcp add ccxt -- npx -y ccxt-mcp

Or in any host's MCP config:

{ "mcpServers": { "ccxt": { "command": "npx", "args": ["-y", "ccxt-mcp"] } } }

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

We are investing a significant amount of time into the development of this library. If CCXT made your life easier and you want to help us improve it further, or if you want to speed up development of new features and exchanges, please support us with a tip. We appreciate all contributions!
