Java Binance API

binance-java-api is a lightweight Java library for interacting with the Binance API, providing complete API coverage, and supporting synchronous and asynchronous requests, as well as event streaming using WebSockets.

• Support for synchronous and asynchronous REST requests to all General, Market Data, Account endpoints, and User stream endpoints.
• Support for User Data, Trade, Kline, and Depth event streaming using Binance WebSocket API.

1. Install library into your Maven’s local repository by running mvn install
2. Add the following Maven dependency to your project’s pom.xml :

Alternatively, you can clone this repository and run the examples.

There are three main client classes that can be used to interact with the API:

These can be instantiated through the corresponding factory method of BinanceApiClientFactory , by passing the security parameters API-KEY and SECRET , which can be created at https://www.binance.com/userCenter/createApi.html.

If the client only needs to access endpoints which do not require additional security, then these parameters are optional.

Once the client is instantiated, it is possible to start making requests to the API.

Check server time

Market Data endpoints

Order book of a symbol

Compressed/Aggregate trades list of a symbol

Weekly candlestick bars for a symbol

Latest price of a symbol

Getting all latests prices

Account Data endpoints

Get account balances

Get list of trades for an account and a symbol

Get account open orders for a symbol

Get order status

Placing a MARKET order

Placing a LIMIT order

Canceling an order

In order to be able to withdraw programatically, please enable the Enable Withdrawals option in the API settings.

Fetch withdraw history

Fetch deposit history

Get deposit address

User stream endpoints

Start user data stream, keepalive, and close data stream

Initialize the WebSocket client

Handling web socket errors

Each of the methods on BinanceApiWebSocketClient , which opens a new web socket, takes a BinanceApiCallback , which is called for each event received from the Binance servers.

The BinanceApiCallback interface also has a onFailure(Throwable) method, which, optionally, can be implemented to receive notifications if the web-socket fails, e.g. disconnection.

Closing web sockets

Each of the methods on BinanceApiWebSocketClient , which opens a new web socket, also returns a Closeable . This Closeable can be used to close the underlying web socket and free any associated resources, e.g.

Listen for aggregated trade events for ETH/BTC

Listen for changes in the order book for ETH/BTC

Get 1m candlesticks in real-time for ETH/BTC

Keep a local depth cache for a symbol

Please see DepthCacheExample.java for an implementation which uses the binance-java-api for maintaining a local depth cache for a symbol. In the same folder, you can also find how to do caching of account balances, aggregated trades, and klines/candlesticks.

Listen for changes in the account

To make an asynchronous request it is necessary to use the BinanceApiAsyncRestClient , and call the method with the same name as in the synchronous version, but passing a callback BinanceApiCallback that handles the response whenever it arrives.

Get latest price of a symbol asynchronously

Placing a LIMIT order asynchronously

Every API method can potentially throw an unchecked BinanceApiException which wraps the error message returned from the Binance API, or an exception, in case the request never properly reached the server.

Automate your workflow from idea to production

GitHub Actions makes it easy to automate all your software workflows, now with world-class CI/CD. Build, test, and deploy your code right from GitHub.

Linux, macOS, Windows, ARM, and containers

Hosted runners for every major OS make it easy to build and test all your projects. Run directly on a VM or inside a container. Use your own VMs, in the cloud or on-prem, with self-hosted runners.

Matrix builds

Save time with matrix workflows that simultaneously test across multiple operating systems and versions of your runtime.

Any language

GitHub Actions supports Node.js, Python, Java, Ruby, PHP, Go, Rust, .NET, and more. Build, test, and deploy applications in your language of choice.

Live logs

See your workflow run in realtime with color and emoji. It’s one click to copy a link that highlights a specific line number to share a CI/CD failure.

Built-in secret store

Automate your software development practices with workflow files embracing the Git flow by codifying it in your repository.

Multi-container testing

Test your web service and its DB in your workflow by simply adding some docker-compose to your workflow file.
