API: get all unique pageview

Hello everybody,
I try to get all unique pageview in subject to the Page URL.
Therefore I use Actions.getPageUrls. But then I just get the first level.
For instance if I call this:
piwik.org/demo/index.php?module=API…_auth=anonymous
Thus I get trac but not trac/timeline

Thanks,
Andi

you can add expanded=1 in the URL (see the list of parameters in http://dev.piwik.org/trac/wiki/API/Reference#Actions )
