How to get follow status on Instagram without API?

Question

API

Hello.
You need to get the status of a subscription to your Instagram account.
https://www.instagram.com/instagram/?__a=1
This page contains a JSON array with account data, among them there is a key with the value "followed_by_viewer": false/true
Actually, the question itself is: if I get the content of the page through
file_get_contents();
that value is always equal to false, respectively. How can I make sure that by clicking on the button, this page was viewed through the currently authorized Instagram account? And of course, you need to pull out the content of the page.
