CORS compliant API to access Instagram's public data

Instagram Proxy API: Instagram's Public Data as an API.

This builds over the Instagram's public API to provide more functionality and provides a CORS complaint reverse instagram proxy service. Try Here: https://igpi.ga/whizzzkid/media/?count=3

The Problem.

A user's public data on Instagram can be accessed on https://www.instagram.com/<user>/media/ but there are are a lot of problems with this service.

1. The Service is not CORS compliant. i.e. You cannot fetch json directly and the services refuses to send you jsonp data.
2. It does not support limiting the amount of data being sent. At any moment Instagram will send you 20 images, you cannot control this number.
3. No pagination support. It get's you the first 20 images and leaves you in the dark to figure out what to do next.

The Solution

As of now, the service is running on https://igpi.ga/(Heroku) I am not aware about limits, it's basically running on free tier. If it hits any limit, I'll have to figure that out. But the intended use is to replace http://www.instagram.com with https://igpi.ga/ or https://igapi.ga/.

Requests

Data Type	End Point	Parameters	Sample URL
User Information	/<username>/	__a=1 (advanced enabled)	https://igpi.ga/whizzzkid/?__a=1
User Posts	<username>/media/	callback: <jsonp> count: <number_of_posts> cursor: <next>	https://igpi.ga/whizzzkid/media?count=3
User Posts (Faster)	/graphql/query/	callback: <jsonp> count: <number_of_posts> cursor: <next> *user_id: <user_id>	https://igpi.ga/graphql/query/?user_id=1606740656&count=3
HashTags	/explore/tags/<hashtag>/media/	callback: <jsonp> count: <number_of_posts> cursor:	https://igpi.ga/explore/tags/yyc/media?count=3
HashTags (Convienient)	/graphql/query/	callback: <jsonp> count: <post_count> cursor: <next> *tag: <hashtag>	https://igpi.ga/graphql/query/?tag=yyc&count=3
		*: Required

Response

Each response (except for advanced parameters looks like):

{
  "next": "next page url",
  "posts": [
    {
    },
    ...
  ]
}

There is a lot more info in each posts. Check them out here

Demo

Send a jsonp request to any of the endpoints above to get instagram data. A simple example in jQuery will be:

$.ajax({
  url: "https://igpi.ga/explore/tags/yyc/media",
  dataType: "jsonp",
  data: { count: 3 },
  success: function (json){
    for(var i in json.posts) {
      var img = document.createElement("IMG");
      img.src = json.posts[i].display_url;
      document.body.appendChild(img);
    }
  }
});

Authentication

NO AUTH REQUIRED, that's the best part, you can access all of instagram's public data without authentication or registering an app. Private data returns nothing. However private data maybe accessible using instagram's api if the user is logged in.

# The following returns data *only* if the user is logged in.
https://www.instagram.com/<private_user>/media/

# The following will always return nothing for private users.
https://igpi.ga/<private_user>/media/

Running on local

Clone the repo and change to the cloned directory. Run:

$ npm install
$ npm run dev

To run prod instance, run:

$ npm run prod

Limits

These apply to the service hosted on: https://igpi.ga and https://igapi.ga

• post fetch limits to 25 (Look for FETCH_COUNT_LIMIT).
• Also all requests with Referer: Undefined will be denied access.

You're free to fork this repo and change flags to disable those limits.

Inspiration

The idea came into being after reading some discussion here.

Updates

Jul 06, 2017: Over 300,000 requests served in last 30 days :)

The logs have gone wild, the sheer number of requests are amazing for this service is running on the free heroku tier. In the last 30 days we have serviced more than 300,000 requests to this API. Check this graph out:

At first I was surprized with this number and was inclined towards thinking that someone was trying to scrape instagram using this API. Turns out I was wrong, a really popular asian website is using this service on their website. I am in talks with them to move this traffic to a dedicated separate instance of this service.

July 11, 2017: Served 440,000+ requests in last 30 days. Heroku suspended my account.

OMFG, this shit just got out of hand:

July 12, 2017: Moved all services to igpi.ga ('a' removed). Blacklist added.

Oct 26, 2017: Undefined referers will not be served at prod.

Both production urls igapi.ga nd igpi.ga will no longer serve content to undefined referers. Your requests will need to explicitly provide referer meta data in the headers. If you're using this service on your website, your browser will automatically handle this, so no change will be required on your part.

Nov 08, 2017: Media Queries No Longer Working

Instagram seems to have patched the media endpoints and now they resolve to 404-pages, however the advanced params still work as of now. So in short, instead of using https://igpi.ga/whizzzkid/media/?count=3 (which won't work) use https://igpi.ga/whizzzkid/?__a=1 and get the data from user.media.nodes object. I'll try figuring the solution around to this.

Nov 10, 2017: Workaround in affect, this is purely experimental.

I am trying to query instagram's GQL servers to rebuild responses. These can be accessed like: https://igpi.ga/graphql/query/?user_id=<user_id>&count=<post_count>. e.g. https://igpi.ga/graphql/query/?user_id=1606740656&count=3

User id can be found here: https://www.instagram.com/whizzzkid/?__a=1 I'll be working on extracting this next.

Nov 12, 2017: Experimental workround seems effective.

The workaround implemented by hacking the GQL queries seems effective. The proxy has been running smooth, so I proted the old endpoints to utilize this. It's undertstandable that this will take twice as longer. But again, it works!

Nov 14, 2017: Enabling undefined referrers for user testing.

Since, IG disable /media urls, undefined referrers will be enabled for a while for perople to test this out.
