Getting the token balances of an account is an essential task when dealing with cryptocurrencies, as it allows you to know the amount of tokens that an account holds. The Web3 APIs from Chainbase provide the ability to get all transactions and account balances in a straightforward way. By following the steps below, you can seamlessly get the native token balances of an account on a certain chain through a single API call using Chainbase API.

​
Overview - Tools you need to work with Chainbase

  1. A free account at Chainbase with an API key.
  2. An IDE. Our examples are shown in JavaScript, you can use VS Code as your IDE for example.
  3. A known wallet address as your input.

​
Step 1: Set up a free account at Chainbase

To better leverage the ability that Chainbase provides, you can register here for a free account and access to different APIs and data cloud. After logging into Chainbase, visit the dashboard to get an overview. Create a new project in the console and get an API key.

​
Step 2: Write script using Chainbase API

  1. Using fetch in JavaScript.
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
wallet_addr = '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045'; // Take Vitalik's wallet address as an example.

fetch(`https://api.chainbase.online/v1/account/balance?chain_id=${network_id}&address=${wallet_addr}`, {
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
}).then(response => response.json())
    .then(data => console.log(data.data))
    .catch(error => console.error(error));
  1. Using axios in JavaScript. You need to install axios using npm install axios --save in the terminal first.
network_id = '1'; // See https://docs.chainbase.com/reference/supported-chains to get the id of different chains.
wallet_addr = '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045'; // Take Vitalik's wallet address as an example.

const axios = require('axios');
const options = {
    url: `https://api.chainbase.online/v1/account/balance?chain_id=${network_id}&address=${wallet_addr}`,
    method: 'GET',
    headers: {
        'x-api-key': CHAINBASE_API_KEY, // Replace the field with your API key.
        'accept': 'application/json'
    }
};
axios(options)
    .then(response => console.log(response.data.data))
    .catch(error => console.log(error));

​
Step 3: Print native token balances

Chainbase API Get native token balances takes the chain id and wallet address as parameters, and returns the value of native token balances. To get data printed, run command node <filename>.js in the terminal. In this case, the native token balances of Vitalik’s wallet on Ethereum is 0x122b7e019d9a0431a15 by the time of Mar. 17th, 2023.
