How do you implement a simple search, view and download in a PHP web app?

Hi guys, I am new to web development and API’s and recently I have been trying to implement something like this(Announcing the Sketchfab download API: a search bar for the 3D world - YouTube) into my PHP(Laravel) web application. I’m very new to cURLS and I tried following this(Data API v3 with PHP - Developers - Sketchfab) and modifying it a little but can’t seem to get it to work. I was wondering if there is a beginner’s guide to making it? Appreciate any help!
