Analytics api returning empty data for high volume load test

is it possible to get real time analytics data during a massive jmeter load test? we are running 10k concurrent calls and the api endpoint /api/v2/analytics/conversations/details/query returns empty array. the status code is 200 ok but no data. i am using python requests library version 2.31.0. the request body has time range of last 5 minutes.

{
 "timeRange": {
 "from": "2023-10-27T10:00:00.000Z",
 "to": "2023-10-27T10:05:00.000Z"
 },
 "view": "summary",
 "groupBy": ["direction"]
}

the data appears in the gui after 10 minutes but for my load test validation i need it immediately. is there a different endpoint for raw data or is this a known latency issue with the analytics engine? we are on genesys cloud edition enterprise. the api rate limit is not hit. i checked the headers and retry after is not present. please advise on how to verify call counts in real time without relying on the gui.
