Come on, it's web we're talking about here. How difficult is it going to be to scrape the data and present it in a nice format to the user? I bet apps will show up that do just that very quickly.
There’s documentation usually with an API and you have changelogs. If you scrape the website, if there is a change in the UI, it will break your product. So it is feasible, but it will make all products worse and harder to maintain.
