📱User Data

Learn how to fetch user data using Airstack Hubs API.

Get Specific User Data By FID

You can get user data by a specific FID by using Airstack Hubs API with the code below:

import {
  Metadata,
  getSSLHubRpcClient,
} from "@farcaster/hub-nodejs";
import { config } from "dotenv";

config();

const client = getSSLHubRpcClient("hubs-grpc.airstack.xyz");

client.$.waitForReady(Date.now() + 5000, async (e) => {
  if (e) {
    console.error(`Failed to connect to the gRPC server:`, e);
    process.exit(1);
  } else {
    console.log(`Connected to the gRPC server`);
    const metadata = new Metadata();
    // Provide API key here
    metadata.add("x-airstack-hubs", process.env.AIRSTACK_API_KEY as string);

    // Fetch user data with `getUserDataByFid`
    const userDataRes = await client.getUserData(
      { fid: 6833, user_data_type: 1 },
      metadata
    );
    console.log(userDataRes?.value);
    // After everything, close the RPC connection
    client.close();
  }
});

import axios from "axios";
import { config } from "dotenv";

config();

const main = async () => {
  const server = "https://hubs.airstack.xyz";
  try {
    const response = await axios.get(`${server}/v1/userDataByFid?fid=6833&user_data_type=1`, {
      headers: {
        "Content-Type": "application/json",
        // Provide API key here
        "x-airstack-hubs": process.env.AIRSTACK_API_KEY as string,
      },
    });
  
    console.log(response);
  
    console.log(json);
  } catch (e) {
    console.error(e);
  }
}

main();
