Zabbix Json Api get health of host or hostgroup - json

Question

I am currently trying out Zabbix 2.4 json api and can connect get alerts and triggers but I'm having trouble finding a way to check if a given hostgroup contains no open errors and is thereby healthy. A simple way to check this doenst seem to exist? I have searched stackoverflow, google and Zabbix documentation. any clues as to tackeling this question? The following reuqest gives me errors but no way to tell if errors are still open.
{
"jsonrpc": "2.0",
"method": "alert.get",
"params": {
"output": "extend",
"groupids": "83",
"time_from": "1441065600"
},
"auth": "ZZZZZZZZZZZZZZZZZZZZZZZZZ",
"id": 1
}
Update: (solved)
$resource = "http://zabbix/api_jsonrpc.php"
$body = '
{
"jsonrpc": "2.0",
"method": "trigger.get",
"params": {
"active": 1,
"only_true": "1",
"monitord": 1,
"selectGroups": 1,
"output": "extend",
"expandDescription": "1",
"selectGroups": "1",
"groupids": 83, <---- this field changes :)
"filter": {
"value": 1,
"priority": [3,4,5] <----- filter off low prios
},
"sortfield": "priority",
"sortorder": "DESC"
},
"auth": "ZZZZZZZZZZZZZZZZZZZZZZZZZ",

}

Use active triggers of host/group. Some my code, which I use:
zapi.trigger.get(only_true=1,
skipDependent=1,
monitored=1,
active=1,
output='extend',
expandDescription=1,
selectGroups=1,
expandData='host',
hostids=<host_id>,
sortfield='priority',
sortorder='DESC',
filter={"value": 1, "priority": ['4','5']}
)
