How to get Soundcloud embed code by soundcloud.com url

Question

I have been researching for hours with no luck to get it worked. Basically I have a cms in which users can put soundcloud url like this "https://soundcloud.com/cade-turner/cade-turner-symphony-of-light", then the page can show an embedded iframe. I have red the api docs for a while but couldn't find anything relavant. This post here have talked but i just didn't quite understand the answers and I checked oEmbed and oEmbed reference but couldn't find proper example. Any one has any more hints?

Edit: Thanks to Jacob's answer, I finally managed to do it by using ajax.

var trackUrl = 'THE_URL';
var Client_ID = 'CLIENT_ID';//you have to register in soundcound developer first in order to get this id 
$.get(//make an ajax request
    'http://api.soundcloud.com/resolve.json?url=' + trackUrl + '&client_id=' + Client_ID, 
    function (result) {//returns json, we only need id in this case
        $(".videowrapper, .exhibitions-image, iframe").replaceWith('<iframe width="100%" height="100%" scrolling="no" frameborder="no" src="https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/' + result.id +'&amp;color=ff6600&amp;auto_play=false&amp;show_artwork=true"></iframe>');//the iframe is copied from soundcloud embed codes
    }
);

I found this in my codesnippets for exactly your purpose, even withouth having to register a client ID.

//Get the SoundCloud URL
$url="https://soundcloud.com/epitaph-records/this-wild-life-history";
//Get the JSON data of song details with embed code from SoundCloud oEmbed
$getValues=file_get_contents('http://soundcloud.com/oembed?format=js&url='.$url.'&iframe=true');
//Clean the Json to decode
$decodeiFrame=substr($getValues, 1, -2);
//json decode to convert it as an array
$jsonObj = json_decode($decodeiFrame);

//Change the height of the embed player if you want else uncomment below line
// echo $jsonObj->html;
//Print the embed player to the page
echo str_replace('height="400"', 'height="140"', $jsonObj->html);
