Example Request and Response

Prerequisite: You will need to install the Alchemy SDK before making requests with it.

The commands for installing it using npm or yarn are given below:

npm install alchemy-sdk@latest

yarn add alchemy-sdk@latest

Request

Here is an example of how to make a getMintedNfts request using the Alchemy SDK:

// Imports the Alchemy SDK
const { Alchemy, Network } = require("alchemy-sdk");

// Configures the Alchemy SDK
const config = {
  apiKey: "demo", // Replace with your API key
  network: Network.ETH_MAINNET, // Replace with your network
};

// Creates an Alchemy object instance with the config to use for making requests
const alchemy = new Alchemy(config);

// Example of using the new getMintedNfts method
const main = async () => {
  // Address for the NFT owner (can be in ENS format).
  let address = "vitalik.eth";

  // Additional options for the request. (Optional)
  let options = {
    /**
     * List of NFT contract addresses to filter mints by. If omitted, defaults to
     * all contract addresses.
     */
    contractAddresses: ["0x57f1887a8BF19b14fC0dF6Fd9B2acc9Af147eA85"],
    /**
     * Filter mints by ERC721 vs ERC1155 contracts. If omitted, defaults to all
     * NFTs.
     */
    tokenType: "ERC721",
  };

  // Calling the getMintedNfts method
  let mintedNfts = await alchemy.nft.getMintedNfts(address, options);

  // Logging the response to the console
  console.log(mintedNfts);
};

main();
