When I am call a route task like this:

routeTask = new esri.tasks.RouteTask("");

What are the limitations of this through the API (if any)? Do I need a ArcGIS online account or is it free to use with the API?
What if I have my own server with ArcGIS Server on it? Do I need the Network analyst extension?
At first glance it does not seem to do any validation from arcgis online for an account when I call it from the API?
