How to get a paid subscription to a channel in youtube api?

Question

Google

My task is to check if the user has a paid youtube subscription to a specific channel and find out the date of the last renewal of the subscription. There is no access to the channel, therefore, authorization must occur through the user.

I have already climbed all the api, but I can’t find a solution for my task.
