MarketPress eCommerce API + Stripe Connect

In a multisite scenario with a global cart, MarketPress eCommerce + Stripe Connect is the perfect fit for this when it comes to collecting a fee on transactions in your network. Why is this not a thing yet and is there any plans to do this?

Secondly, in the MarketPress eCommerce description, it states "Advanced API support for developers". Where is that API documentation exactly and can Stripe Connect integration be achieved via this API?
