Fetch and Transfer NFTs

You started creating wallets. Now it's time to build the frontend for your users to interact with them.

Visualizing the NFTs

The following API retrieves the NFTs stored in a wallet so you can display them in your frontend:

const fetch = require('node-fetch');

const url = 'https://staging.crossmint.com/api/v1-alpha1/wallets/chain:wallet/nfts?page=xx&perPage=xx';
const options = {
  method: 'GET',
  headers: {
    accept: 'application/json',
    'X-CLIENT-SECRET': '<YOUR_CLIENT_SECRET>',
    'X-PROJECT-ID': '<YOUR_PROJECT_ID>'
  }
};

fetch(url, options)
  .then(res => res.json())
  .then(json => console.log(json))
  .catch(err => console.error('error:' + err));

Parameter	Type	Description
`chain`	string	`arbitrum`, `arbitrumnova`, `base`, `bsc`, `cardano` ,`ethereum`, `optimism`, `polygon`, `solana`, and `zora`
`walletAddress`	string	Wallet address whose content you want to fetch
