Data from Grafana doesn't match with /ds/query Api data

System Information
Mac OS 13.1
postman version v10.12

Hey guys, I’m trying to fetch data from metrics, traces and logs using postman via grafana’s API api/ds/query

The data that i see in grafana website and the data i get from api response is not matching
for example website shows data as 13.119329643435776
the Api response is 6.475663496181369

I tried to give epoch in postman but it doesn’t seems to work either. However the values are close
13.08791031781584 if given range in epoch

Thanks in advance
