I'm getting feed from this link. I want to get only first five items from feed. Instead of that I'm getting all of the items from feed. How can I get first five items only ?. Should I pass any parameters with URL ?

HTTP.get('https://buzz.machaao.com/feed',
  (err, res) => {
    if(err) {
      console.log(err);
    }
    else {
      console.log(res);
    }
});
