Historical Intraday data for Nifty options including IV

Hi,

Does anyone here know where we can get Historical intraday OHLC data for Nifty and Banknifty options and futures including OI and IV?

You can get historical open interest here > https://fnoanalysis.com/oi/option_chain_hist.php

Hey, this definitely looks interesting. Thank you! I was looking for data in the same format as below (screenshot from the same link you shared)

But, when i click download, getting 403 error. Also is there anyway i can get all files (only for nifty and banknifty) for all days at once, instead of going through that whole process for each day’s file?
