Acquiring mechanism when we act as an intermediary?

Question

Payment systems

Hello gentlemen!
There is a site that is an intermediary for the buyer and recipient. When the buyer pays a certain amount to the recipient, the site, as an intermediary, must take its percentage.
Tell me, please, what is the name of such a mechanism and what online aggregators have this functionality?
