Java SDK for CryptoAPIs.io

You can get API key here.

Getting started

Add the relevant dependency to your project:

Maven

Java 8:

<dependency>
    <groupId>io.cryptoapis</groupId>
    <artifactId>cryptoapis-java-client</artifactId>
    <version>1.3.0</version>
</dependency>

Gradle

Java 8:

compile("io.cryptoapis:cryptoapis-java-client:1.3.0")

How to use

final String apiKey = "your API key";
CryptoApis caClient = new CryptoApis(apiKey);

// Choose API connection and network
final Exchanges exchanges = caClient.connectToExchanges();

final Ethereum eth = caClient.connectToEth(CryptoApisConstants.ETHEREUM_MAINNET);

final Bitcoin btc = caClient.connectToBtc(CryptoApisConstants.MAINNET);

final Bitcoin_Cash bch = caClient.connectToBch(CryptoApisConstants.MAINNET);

final Litecoin ltc = caClient.connectToLtc(CryptoApisConstants.MAINNET);

final Dogecoin doge = caClient.connectToDoge(CryptoApisConstants.MAINNET);

Ethereum examples

Generate new address

final AddressService ethAddressService = eth.getAddressService();

ApiResponse res = ethAddressService.generateNewAddress();
System.out.println(res.getResponse());

It will print the following:

{
  "payload": {
      "address": "0xb8e51b75a8ab6995b2e11938fed3b05837ec5fa2",
      "privateKey": "5d06b11d276e169d2fa2ced94d327902ee954ff47e31bcbf0aa4957a829a0aed",
      "publicKey": "303727940fca8f9b1f580908246aa980f9ee2aa9ecc379cbaf6a80f0050c1a2cdd7a467c1e564a2e272fb5b1958320ca11ca79b9cdfaf2bd74e6decd2592daa8"
  }
}

Generate new account

final String password = "your password - l3tt3rs and d1g1ts";
ApiResponse res = ethAddressService.generateAccount(password);
System.out.println(res.getResponse());

If will print the following:

{
    "payload": {
        "success": "keystore saved",
        "address": "0x14eefa06e6f617ba9df050d7f9415e5bd0f11d34"
    }
}

If an error occurs, it will print the following (e.g. your password is weak):

{
  "meta":
    {
      "error":
        {
          "message": "Password is too weak! It should be at least 7 characters and should contain at least one letter and one digit",
          "code": 15
        }
    },
  "statusCode": 400
}

Get address balance

final String address = "0xd6cB6744B7f2Da784c5aFd6B023D957188522198";
ApiResponse res = ethAddressService.getAddressBalance(address);
System.out.println(res.getResponse());
{
