Quickstart

A step-by-step guide on how to query NFT data using Javascript fetch.

For this guide, we will be using fetch

Javascript Fetch

node-fetchis a lightweight, common module that brings the Fetch API to Node.js and allows us to make our HTTP requests. You can see the documentation for more info: https://www.npmjs.com/package/node-fetch

Installation

Run the following command to install node-fetch with npm and yarn
With npm

npm install node-fetch

With yarn

yarn add node-fetch

Sample Code

In your project directory, you can create a new file called fetch-nftgo.js using your favorite file browser, code editor, or just directly in the terminal using the touch command like this.

touch fetch-nftgo.js

and then paste the following code snippet in to explore the get_nft_basic_info method:

import fetch from 'node-fetch';

// Replace with your NFTGo API key:
const apiKey = "YOUR-API-KEY";
const options= {
  method: 'GET',
  headers: {
    accept: 'application/json',
    'X-API-KEY': apiKey
  }
};
// Replace with the contract address you want to query:
const contractAddress = "0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d"
// Replace with the token id you want to query:
const tokenId = "4495"
const url = `https://data-api.nftgo.io/eth/v1/nft/${contractAddress}/${tokenId}/info`;

// Make the request and print the formatted response:
fetch(url, options)
  .then(res => res.json())
  .then(json => console.log(json))
  .catch(err => console.error('error:' + err));

From your command line, you can execute the script with:

node fetch-nftgo.js

Your output should look like the following:
