Java Binance Unofficial API Client

This library is designed to help you make your own projects that interact with the Binance API. This project seeks to have complete API coverage including User Data Streams and WebSockets for Binance Cryptocurrency Exchange

If you are seeking for a version with Android 4 support, please take a look at https://github.com/shufps/java-binance-api

Getting Started

with Maven

Add the following Maven dependency to your project's pom.xml:

<dependency>
  <groupId>com.webcerebrium</groupId>
  <artifactId>binance-api</artifactId>
  <version>1.0.9</version>
</dependency>

with Gradle

compile group: 'com.webcerebrium', name: 'binance-api', version: '1.0.9'

with Grapes

@Grapes([ 
@Grab(group = 'com.webcerebrium', module = 'binance-api', version = '1.0.9')
])

with latest source code

After git clone, please run gradle jar, which will result in having jar under build/distribution folder. compilation you will have jar in your folder, which could be included as your dependency like this:

dependencies {
    compile files('libs/binance-api-1.0.9.jar')
}

Example of Application

import com.webcerebrium.binance.api.BinanceApi;
import com.webcerebrium.binance.api.BinanceApiException;

try {
  BinanceApi api = new BinanceApi();
  System.out.println("ETH-BTC PRICE="   api.pricesMap().get("ETHBTC"));
} catch (BinanceApiException e) {
  System.out.println( "ERROR: "   e.getMessage());
}

Setting up API KEYS

For API keys you can set an environment variables or java Virtual Machine properties BINANCE_API_KEY, BINANCE_SECRET_KEY, as well as setting up these variables in application.properties resource file of your project

Logging

Logging configuration can be corrected in logback.xml files. To suppress requests/response logging, you might want to increase logging level for BinanceRequest component:

<logger name="com.webcerebrium.binance.api.BinanceRequest" level="WARN" />

Debugging Library from Source

If you cloned this GITHUB repository, the following tips might be useful:

Running tests

If you cloned this repository, tests with API coverage could be launched with gradle test. Before running, make sure API keys are set as described above. For successful trading tests passing, it is desired to have some BTC, ETH and BNB on your account.

Running in Eclipse

This project uses Lombok. You will need to install lombok for Eclipse to make the project compile in Eclipse. It will compile via gradle just fine without this additional installation step.

Running in Intellij IDEA

This project uses Lombok. You will need to install corresponding plugin and enable Annotation processing in your Compiler settings. It will compile via gradle just fine without this additional installation step. To start, import current directory as Gradle project.
