This guide demonstrates how to use the Neynar SDK to get trending casts on Farcaster. 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 { Configuration, NeynarAPIClient } from "@neynar/nodejs-sdk";
import { FeedType, FilterType } from "@neynar/nodejs-sdk/build/api";

// make sure to set your NEYNAR_API_KEY .env
// don't have an API key yet? get one at neynar.com
const config = new Configuration({
  apiKey: process.env.NEYNAR_API_KEY,
});

const client = new NeynarAPIClient(config);
Then fetch the global trending Farcaster casts: 
const feed = await client.fetchFeed({
    feedType: FeedType.Filter,
    filterType: FilterType.GlobalTrending,
    limit: 1,
  })

console.log(feed);

   }
}
To fetch the next page of the feed, use the cursor: 
const nextFeed = await client.fetchFeed({
    feedType: FeedType.Filter,
    filterType: FilterType.GlobalTrending,
    limit: 1,
    cursor: feed.next.cursor,
  })
It’s that easy to get trending casts in Farcaster!
