import { init, useQuery } from "@airstack/airstack-react";

init("YOUR_AIRSTACK_API_KEY");

const query = `YOUR_QUERY`; // Replace with GraphQL Query

const Component = () => {
  const { data, loading, error } = useQuery(query);

  if (data) {
    return <p>Data: {JSON.stringify(data)}</p>;
  }

  if (loading) {
    return <p>Loading...</p>;
  }

  if (error) {
    return <p>Error: {error.message}</p>;
  }
};

Airstack provides an AI solution for you to build GraphQL queries to fulfill your use case easily. You can find the AI prompt of each query in the demo's caption or title for yourself to try.

Get NFT Balances of User(s)

You can use Airstack to fetch NFT balance of user(s) across multiple chains, e.g. Ethereum, Base, Degen Chain, and other Airstack-supported chains, by using the TokenBalances API and providing an array of users' 0x address, ENS domain, cb.id, Lens profile, or Farcaster fname/fid to owner input:

Try Demo

Code

query MyQuery {
  Ethereum: TokenBalances(
    input: {
      filter: {
        owner: {
          _in: [
            "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"

        }
        tokenType: { _in: [ERC1155, ERC721] }
      }
      blockchain: ethereum
      limit: 50
