How to decrypt public data of instagram users?

Question

API

Good day!

I get the data of instagram users through the request

https://www.instagram.com/someone/?__a=1

I was able to get the number of publications of the account, subscribers and subscriptions from here.
Can you help me figure out what other data the request contains?
Is there a manual for this request? Where to read about the content of this request?

The problem is this: I made a request for my account and went to Instagram to check if some values ​​are "false" or incorrect, or maybe that's how it was intended. In general, I'm confused, are there specialists here who can explain what other data I can pull out of the request?

Answer 1

so everything is visible there,
what exactly is not clear?
