To get ENS domains owned by a wallet address, you can use Chainbase Get ENS domains API. If the wallet doesn’t have any ENS domains, the data field of the response will be null.

​
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 = '0x57511688c0ca7Cc7C25B90aE51C62B64652136Ac'; // Take our CTO Xiaocong's wallet address as an example.

fetch(`https://api.chainbase.online/v1/account/ens?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 = '0x57511688c0ca7Cc7C25B90aE51C62B64652136Ac'; // Take our CTO Xiaocong's wallet address as an example.

const axios = require('axios');
const options = {
    url: `https://api.chainbase.online/v1/account/ens?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 ENS domains

Chainbase API Get ENS domains takes the chain id and wallet address as parameters, and returns all the ENS domains owned by the wallet. To get data printed, run command node <filename>.js in the terminal. In this case, the ENS domains of Xiaocong’s wallet on Ethereum are as follows. 
[
  {
    "address": "0x57511688c0ca7cc7c25b90ae51c62b64652136ac",
    "expiration_time": "2023-04-17T14:19:21Z",
    "name": "lxcong",
    "owner": "0x57511688c0ca7Cc7C25B90aE51C62B64652136Ac",
    "registrant": "0x57511688c0ca7cc7c25b90ae51c62b64652136ac",
    "registrant_time": "2022-04-17T08:30:09Z",
    "resolver": "0x4976fb03c32e5b8cfe2b6ccb31c09ba78ebaba41",
    "text_records": {},
    "token_id": "63135721284494715790867739452503301817186787830065141439742276093364926543362"
  }
]
