I am using Alchemy API to handle fetching NFTs and their metadata in my platform. It has valuable methods, such as retrieving all issued NFTs of a collection or all owned NFTs of an address within a specified network.

However, I need to get the NFTs that a specific address owns from a target NFT collection. Is there a solution to this in Alchemy docs ( since I did not find it )? Or do I have to filter Alchemy's response by the Javascript filter( ) method?

This is the script I am using for this purpose.

  const [ nfts, setNfts ] = useState(null)

  const settings = {
    apiKey: 'Alchemy API Key', 
    network: Network.MATIC_MAINNET, 

  const alchemy = new Alchemy(settings);

  useEffect(() => {
  }, [])

  const fetchNfts = async () => {
    console.log("Fetching NFTs ...");
    const response = await alchemy.nft.getNftsForContract("0x220A95bdE3ffa364050FFe07b436869C08787eC8");

(1) Get all the NFTs of an address owned within a specific network by ( You have to do the network configuration earlier ):

await alchemy.nft.getNftsForOwner(address)

(2) Then store the response ( It's an object } in a state variable

(3) Within the return section of your component, try to map over the stored array (state variable ) and filter them out based on each NFT's contract address like:

    nfts.map((nft, i) => (
        <div key={i}>
            <img src={nft.image} className="rounded" />
                <p>Price - {nft.price} Matic</p>

Each nft ( from the array we received from Alchemy and stored in a stat variable ) has some valuable properties that you can use based on the needs of your project


I am not familiar with Alchemy's API, but you could definitely do this by building a subgraph for this, to index the data specific to your needs. And then query the data from a frontend like you would from Alchemy's API.


With this logic:

    const balance = await NFT.balanceOf(walletAddress);

    const getTokensId = async (recipient, index) => {
        try {
            const result = NFT.tokenOfOwnerByIndex(recipient, index);
            return result;
        } catch (error) {
            console.log(error, "the error for getTokensId");

You can get the balance and the tokenId owner of a specific contract.
