Check out this Getting started guide to learn how to set up your environment and get an API key. First, initialize the client: 
// npm i @neynar/nodejs-sdk
import { NeynarAPIClient } from "@neynar/nodejs-sdk";

// make sure to set your NEYNAR_API_KEY .env
// don't have an API key yet? get one at neynar.com
const client = new NeynarAPIClient(process.env.NEYNAR_API_KEY);
First we fetch the custody address for a user: 
const FID = 3;
const response = await client.lookupCustodyAddressForUser(FID);
const custodyAddress = response.result.custodyAddress;
Then we fetch the relevant mints for the user: 
// Farcats contract address
const contractAddress = "0x9340204616750cb61e56437befc95172c6ff6606";
const relevantMints = await client.fetchRelevantMints(
  custodyAddress,
  contractAddress
);

console.log(relevantMints);
Example output: 
{
  "mints": [
    {
      "minter": {
        "object": "user",
        "fid": 129,
        "custody_address": "0xf6fd7deec77d7b1061435585df1d7fdfd4682577",

          }
        },

          "0x925afeb19355e289ed1346ede709633ca8788b25"
        ],
        "active_status": "active"
      },
      "tx_hash": "0x2ed2ebb4b048677133eda3a8609bae694d2ba730c7fa2082691f508e711b6075",
      "block_number": 17610874,
      "contract_address": "0x9340204616750cb61e56437befc95172c6ff6606",
      "token_id": "353"
    },
    // other mints
]
}
It’s that easy to get relevant mints for a Farcaster user!
