We have a website that currently displays all of it's (fast changing) information for free and we wish to run an experiment where we charge a fixed fee for a single day's use... if the experiment has a promising result we may go to town with all sorts of complex subscription options but just for this test we're looking for a cheap and cheerful mechanism. We thought we could just have a single password of the day (with no username) for the whole site. Yes, this could be shared between users but we're not worried about this just for the experiment. So what we want is a "buy now" button which somehow results in the user being given the password of the day... either on the website or via an email. I dare say Paypal might have a ready made solution for our requirements already but I have no idea what to look up or what documents to read. I am not very expert on server side stuff like nodejs so the less of that the better. Any ideas/advice welcome.
