💳Username Proofs

Learn how to fetch username proofs data using Airstack Hubs API.

Get Username Proofs By Username

You can get username by a specific username 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 uers name proofs data with `getUserNameProof`
    const userNameProofsRes = await client.getUserNameProof(
      { name: new TextEncoder().encode("adityapk") },
      metadata
    );
    console.log(userNameProofsRes.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/userNameProofByName?name=adityapk`, {
      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();

{
  "timestamp": 1670603245,
  "name": "adityapk",
  "owner": "Oi7uUaECifDm+larm+rzl3qQhcM=",
  "signature": "fo5OhBP/ud...3IoJdhs=",
  "fid": 6833,
  "type": "USERNAME_TYPE_FNAME"
}

Get Username Proofs By FID

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

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/userNameProofsByFid?fid=2`, {
      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();

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 uers name proofs data with `getUserNameProofsByFid`
    const userNameProofsRes = await client.getUserNameProofsByFid(
      { fid: 2 },
      metadata
    );
    console.log(verificationRes.value);
    // After everything, close the RPC connection
    client.close();
  }
});
