Analytic API not matching API reports

Im trying to just pull detailed call data, grouped by users, daily...

"timeRange": {
            "timeFrom": "2023-01-26T00:00:00Z",
            "timeTo": "2023-01-26T23:59:59Z"
        }

If I try to set this time range I get this error:

"errorCode": "ANL-305",
            "message": "Interval must be less than time range"

I can pass things like this:

"grouping": {
        "groupBy": "Users",
        "keys": []
    },
    "timeSettings": {
        "timeRange": {
            "timeFrom": "2023-03-23T00:00:00.000Z",
            "timeTo": "2023-03-24T11:59:01.000Z"
        },
        "timeZone": "US/Eastern"
    }

and multiple variations in changing the timeFrom and timeTo -- so long the same Day is not selected...

However, none of the results I get match even close to the Performance Reports, by day, by user, in the admin analytics portal.

This is driving me crazy.
What am I doing wrong?
