With Farcaster data being public, we can see what @vitalik.eth sees on his feed (reverse chronological of following). In this guide, we’ll do exactly that.

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, FeedType, FilterType } 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);

Now, we can fetch the following feed for Vitalik’s FID:

const vitalikFid = 5650;

const feed = await client.fetchFeed(FeedType.Following, {
  fid: vitalikFid,
});

console.log(feed);

Example output:

next: {
  cursor: "eyJ0aW1lc3RhbXAiOiIyMDI0LTEwLTI3IDA1OjQxOjQxLjAwMDAwMDAifQ%3D%3D",
},
}

To fetch the next page of casts, use the cursor:

const nextFeed = await client.fetchFeed(FeedType.Following, {
  fid: vitalikFid,
  cursor: feed.next.cursor,
});

So that’s what @vitalik.eth sees on his Farcaster feed!
