📰 About BlockScan API

Blockscan is a blockchain explorer which provides realtime information on blocks, transactions, tokens, balances and more on XDC network. BlockScan API gives developers direct access to BlockScan explorer data via HTTP GET requests.

Why and when to use BlockScan API

BlockScan API is used when you need to get data from blockchain. By using BlockScan API, you don't need to run our own blockchain node and storing hundreds of gigabytes of blockchain data which is very expensive and unreliable. It can be used to fetch data for wide range of applications from blockchain dashboards to decentralized exchanges.

🔍 API Overview

BlockScan API consists of five main methods:

  • Accounts: get XDC account data like balance, address, txCount etc.

  • Blocks: get XDC blockchain block info

  • Contracts: get contract details and verified contracts

  • Transactions: get list of transactions, transaction details and logs

  • Tokens: get details on XRC20 and XRC721 tokens

🔍 Interact With BlockScan API

In this introduction we will display two main ways to interact with BlockScan API: Swagger UI and via Node.js.

Swagger UI

Swagger UI is a tool to visualize and interact with API. It is great as a learning tool or documentation.

To open XDC BlockScan API Swagger UI go to

Click on one of the dropdowns, in this example /api/tokens. Scroll to bottom of page to find it.

You will see input fields and description of parameters for this request. To unlock requests, click Try it out.

Now fill type field with xrc721, because we are going to search for NFT tokens. In page field type 1 for the first page and set limit to 10. Once it is done, hit Execute.

After waiting a bit, you will receive a response with NFT data from XinFin blockchain.


Run this to install axios package.

npm -i axios

Then create index.js, copy and run this Javascript code.

const axios = require('axios');

  method: 'get',
  url: '',
  headers: {
    'Content-Type': 'application/json'
  .then(function (response) {
    console.log('status code', response.status)
    if (response.status === 200) {

Once completed, you should see account info like this:
