# 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) ```typescript 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}): ${token.quantity}`); } ``` ### Step 2: Get NFT Metadata ```typescript const nfts = await core.client.request({ method: 'qn_fetchNFTs', params: [{ wallet: '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045', contracts: ['0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D'], // BAYC page: 1, perPage: 10, }], }); for (const nft of nfts.result.assets) { console.log(`${nft.name} — Token ID: ${nft.tokenId}`); console.log(` Image: ${nft.imageUrl}`); } ``` ### Step 3: Track ERC-20 Transfers ```typescript const transfers = await core.client.request({ method: 'qn_getWalletTokenTransactions', params: [{ address: '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045',...
