Instagram Media/Feed API - instagram

Question

I am currently looking at Instagram feed integration in a web app.
The offical APIs are: Instagram Graph API and Instagram Platform API.
And then I found one endpoint like https://www.instagram.com/instagram/media/ on SO, here and here, which seems an undocumented (at least I haven't seen it on facebook/instagram document).
It's publicly accessible and you can get a lot of information about the posts including likes and comments.
So my questions are:
Is the https://www.instagram.com/{username}/media/ documented some where?
Is it widely used on the internet?

Answer 1

Its not official API, it may stop working anytime, not a good idea to use in a App. Other Instagram undocumented APIs have stopped working in the past, its good to use for one-off projects but I would not use it in a app/website.

Answer 2

This endpoint has stopped working on November 7 2017. But you can use this other endpoint to get the same results:
GET /users/user-id/media/recent
https://api.instagram.com/v1/users/{user-id}/media/recent/?access_token=ACCESS-TOKEN
Get the most recent media published by a user.
The public_content scope is required if the user is not the owner of the access_token.
REQUIREMENTS
Scope: public_content
PARAMETERS
ACCESS_TOKEN A valid access token.
MAX_ID Return media earlier than this max_id.
MIN_ID Return media later than this min_id.
COUNT Count of media to return.

Answer 3

I wrote small library on typescript. It doesn't require access token or client id.The library uses RegExp under the hood. You can get your photos like this:
import Nanogram from 'nanogram.js';
const instagramParser = new Nanogram();
instagramParser.getMediaByUsername('instagram').then((media) => {
console.log(media);
});
