Pull data from trade ogre api with php

I am trying to pull the price of ada to add to my website.

This is what I’ve tried:

<?php
$content = file_get_contents('https://tradeogre.com/api/v1/markets');

preg_match('#"ADA-USDT":{"initialprice":"(.*)","price":"(.*)"#', $content, $match);
echo $match[2];

?>

I tried and thought it was going to be easy as i have used this code many times!
