body: <p>I am digging into Instagram APIs and find out a URL <code>https://i.instagram.com/api/v1</code> which used by many git repos(some are recently updated) but when I go to Instagram there is no such url available there. Can anyone guide me what is the use of this url and how I can use it because when I hit</p>
  <pre><code>https://i.instagram.com/api/v1/accounts/login/
  </code></pre>
  <p>by POSTMAN i got below message</p>
  <pre class="lang-json prettyprint-override"><code>{
      &quot;message&quot;: &quot;Your version of Instagram is out of date. Please upgrade your app to log in to Instagram.&quot;,
      &quot;status&quot;: &quot;fail&quot;,
      &quot;error_type&quot;: &quot;needs_upgrade&quot;
