Do I need to get Instagram API permissions?

Question

API

To get information from a post, such as (number of likes, comments, views), is it necessary to get permission, namely, describe the whole essence of the process, shoot a video and send them an application?

Answer 1

To get public information about a post in json format, just add the get parameter __a=1 to the post address.
For example:
https://www.instagram.com/p/BuEpOj0nzSF/
https://www.instagram.com/p/BuEpOj0nzSF/ ?__a=1

No, just get this data, it's public
