How to make query more lean and readble

APIs
1

Hi, I am trying to get a list of posts via php (laravel).

I have
$query = (new \Contentful\Delivery\Query())
** ->setContentType(‘posts’)**
** ->setLimit(‘3’);**
$entries = $client->getEntries($query)->getItems();

However, I get a response that takes 1092 ms and jams up the postman and gives me over 5000lines for return. (goodness me)
How can I make this lean, ie get just the data I need. And how do I convert this into an object that is more readable. Everything is protected.

Much appreciated.
