Instagram API review submission - complete app needed?

I just noticed that new Instagram API's sandbox has too many restrictions and I would need to submit review to build my app. I googled to see if there's a way around but looks like using their API would be better than anything.

The app I was going to build requires all the API endpoints that Instagram doesn't allow Sandbox users to access (such as hashtag search and get recent tags). Do I just build one assuming I can get responses from the endpoints? I am pretty confused. Anything would help. Thanks!

Solution

You think you have two options:

Since, instagram allows you get the contents from the user's in the sandbox mode.
Create an App using link and submit for review to get experience with public data available in instagram.
