It’s important for a wallet to view all NFTs it holds. Chainbase offers a specific API endpoint for retrieving all NFTs owned by a wallet address.

​
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 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/nfts?chain_id=${network_id}&address=${wallet_addr}&page=1&limit=5`, {
    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/nfts?chain_id=${network_id}&address=${wallet_addr}&page=1&limit=5`,
    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 NFTs owned by the wallet

Chainbase API Get NFTs owned by address takes the chain id and wallet address as parameters, and returns the NFTs owned by the input wallet. To get data printed, run command node <filename>.js in the terminal. In this case, five of the NFTs owned by Vitalik are as follows.
