Hey @Parthiban_Sub
If we look into the first and second screenshot shared by you, I can see that the data being passed is actually correct. Since you are fetching data in 1 min timeframe, you are getting only one response (since you are fetching data between 09:14 and 09:16)
You are getting the GMT time on EPOCH conversion as 03:45:00 AM which when converted to IST is 09:15:00 AM.
On the third screenshot, do check the validity of Security ID and whether there is data for the same on charts.
Would request you to let us know in case you find any such instances, as the data source for APIs and charts on Dhan remain the same. It is highly unlikely of such instances.
