Zabbix 5 API Query maintenance.get Only Current Window With Specific Tags

[ccsonetwo]

Hey all, a little patience here please. I'm new to the zabbix api and I'm trying to create a query that will return all the current maintenance windows with a specific tag. I've read the documentation and unfortunately I am either not understanding it or having problems with getting it to work.

My query looks like this:

{
    "jsonrpc": "2.0",
    "method": "maintenance.get",
    "params": {
        "groupids": "<gid>",
        "selectTags": [
            "tag",
            "value"
        ],
        "filter": [
            {
                "tags": [
                    {
                        "tag": "<tag1>",
                        "value": "<value1>",
                        "operator": 0
                    }
                ]
            }
        ]
    },
    "auth": "<token>",
    "id": 1
}

Unfortunately this will return all the maintenance windows for the <gid>, expired and with other tags. Is there a way to get just the current maintenance with specific tags? Should I be iterating over the returned maintenance instances instead?

End goal here is to create a script that will return the existing and current maintenance windows that apply to a specific group. Am I using the wrong query?
