What you're looking for is probably the origin-header. All modern browsers send it along if you're doing a cross domain request.

In an ApiController you fetch it like so:

if (Request.Headers.Contains("Origin"))
{
    var values = Request.Headers.GetValues("Origin");
    // Do stuff with the values... probably .FirstOrDefault()
}
