How, without using the API, to monitor the number of subscribers with a Python script?

Question

YouTube

Previously, I used the API posted on Github and Instagram banned accounts, now I can monitor subscribers on my accounts, collect statistics on the number of likes and subscriptions per day.
Is it possible without an API?
If not possible, is it possible to just log in once a day and read the number of subscriptions?
The same question for Youtube, but everything seems to be simpler there.

Answer 1

To be honest, I did not quite understand the essence of the question. If we are talking about reading subscribers, then there are two options: either API or parsing. Parsing can be done without calling the API. I recommend beautifulsoup. Parse very well. Well, or import re in hand.
