If I run get_host_info.php from the V1 api I can see the number of tickets for a host.
Is there a way to get the same ticket counts from the V2 api?
No, I'm sorry. No easily, you could pull the host detection feed and then do some calculations baed on the date values available le to you (LAST FOUND, LAST SCAN, etc) but it's not as straightforward as th v1 API.
