1. Introduction

As the world of Non-Fungible Tokens (NFTs) continues to gain popularity, it becomes essential for wallet owners to have the ability to view all the NFTs they hold. In this article, we will explore how you can retrieve all the NFTs owned by a specific wallet address using Chainbase, a platform that offers a convenient API endpoint called getAccountNFTs.

2. Tools Required to Work with Chainbase

Before we dive into the process, let's ensure we have the necessary tools in place:

1. Chainbase Account and API Key: Start by setting up a free account at Chainbase and obtain an API key. This key will grant you access to the Chainbase API.
2. Integrated Development Environment (IDE): For our examples, we will be using JavaScript, and you can use Visual Studio Code (VS Code) for writing and executing the code.
3. Wallet Address: You will need a wallet address for which you want to obtain the associated NFTs. Make sure you have the address ready before proceeding.

3. Set up a Free Account at Chainbase

To make the most out of Chainbase's capabilities, begin by registering for a free account on our website. Once you've successfully logged in, explore the dashboard to familiarize yourself with the features. Next, create a new project using the console and obtain your unique API key.

4. Write a Script Using Chainbase API

Now that we have our account and API key, we can proceed with writing a script that utilizes the Chainbase API to retrieve the NFTs. Let's consider two options using JavaScript: fetch and axios.

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));

Using Axios in JavaScript

Ensure you have axios installed by running npm install axios --save in the terminal.

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));

5. Print NFTs Owned by the Wallet

The Chainbase API provides the [getAccountNFTs](https://docs.chainbase.com/reference/getaccountnfts) endpoint, which requires the chain ID and the wallet address as parameters. This endpoint returns the NFTs associated with the given wallet address.

To secure and display the NFTs’ data, execute the script in your preferred JavaScript runtime environment. By running the command node <filename>.js in the terminal, you will see the NFTs owned by the provided wallet address.
