API get hostid via inventory alias

[wamsterdam]

Hi,

I know how to retrieve host inventory info for a given hostid via the API using PHP:

$contacts = $api->hostGet(array(
	'output' => 'shorten',
	'filter' => array('hostid' => '10155',
	'selectInventory' => array('contact', 'name', 'alias')
));

but I haven't found out how to retrieve the hostid for a given inventory alias?

TIA,
Wouter
