Searching on JSON pages - php

Question

I am searching products on an e-commerce website using their API. The API returns all the information in JSON format as a response. Each JSON response has 50 items and a URL that has 50 other items and so on. So to match the searched string with product titles, I need to parse all the JSON files sequentially. But if the item to be searched is on the last page, it is taking about 40 minutes to reach there. Can you please help on how I can reduce that time?
My website is currently hosted on localhost(XAMPP).
index.php
$fk = new Flipkart();
$fk->getProductFeedJason($fk->result);
for($i=0; $i<51; $i++)
{
if($fk->flag==1)
break;
$fk->curl($fk->links[$i]);
$fk->getProducts($fk->result, $sstring);
}
