QuickNode Core Workflow B — NFT & Token APIs

Overview

Use QuickNode's NFT and Token APIs to fetch metadata, check balances, and track transfer history. These are QuickNode-specific add-on APIs beyond standard EVM RPC.

Prerequisites

• Completed quicknode-core-workflow-a
• Token and NFT add-ons enabled on your QuickNode endpoint

Instructions

Step 1: Get Token Balances (QuickNode SDK)

import { Core } from '@quicknode/sdk';

const core = new Core({ endpointUrl: process.env.QUICKNODE_ENDPOINT });

// Get all ERC-20 token balances for a wallet
const balances = await core.client.request({
  method: 'qn_getWalletTokenBalance',
  params: [{ wallet: '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045' }],
});
for (const token of balances.result) {
  console.log(`${token.name} (${token.symbol}): ${token.quantity}`);
}

Step 2: Get NFT Metadata

const nfts = await core.client.request({
  method: 'qn_fetchNFTs',
  params: [{
    wallet: '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045',
    : [],  
    : ,
    : ,
  }],
});
 ( nft  nfts..) {
  .();
  .();
}
