Import data from a Reporting Services Webpage?

Hi all, 

 Is it possible to easily import data into SQL Server from a public facing Reporting Services webpage?

I'd like to automate the process so don't want to have to download the Excel / CSV files manually. There's an "atomsvc" file available but I can only find information on importing this into PowerPivot / Excel. 

I'm on 2012 and have access to Integration Services if that would help, but have no real preference on how I solve this problem. 

I'm guessing I could import the Atom feed referenced by the "atomsvc" file as XML data but this seems slightly cumbersome given that the source is also an SQL Server. I'm also a little unsure about how to use authentication in this case. 

So is it a parse XML task or am I missing a much more obvious and simple way to import this data?

Thanks
