I used to work on for a company on a product that did exactly this, but the company stopped working on that product since it didn't go anywhere (API docs seem to still be online though :D https://docs.satoshipay.io/api/). Some small publishers liked it, big ones wanted to force their customers to subscribe (whilst recording their data at the same time).

I really like the general idea though and hope it does make a comeback. I think it would be good for review/test sites especially.
