How to get an extract from the Internet bank?

Question

API

Good afternoon. Interested in the API for downloading statements from the Internet bank clients of large Russian banks.
The list contains but is not limited to the following banks:

• Alfa Bank
  
• VTB 24
  
• Raiffeisen bank
  
• Tinkoff
  
• Sberbank
  
• Opening
  

The task is to make an aggregator of expenses on my cards from all banks.
It seems that Zenmoney had such a feature, but I went there today (the last time was about 2 years ago), I can’t find the connection and how it was done.
In fact, after all, it is necessary to give a login-password-codeSMS and contact the desired URL and get an extract?
Interested in the technical side of the issue, and not a ready-made service that does this to me as a user.
