Scheduled Script jobs has support for the SiteVision API when a start node is selected for the scheduled script job, see example below.
Go to <address/admin> -> Cluster -> Tab Tasks -> Add Script job.
Since some internals of the SiteVision API relies on an actual request, some functionality might not work properly.
If a page (i.e. page, site or article) is selected as start node, SiteVison will try to mimick a request to that page. This will diminish the number of functions that might not work properly.
