Need some help (ICICI Direct, Algo Trading, Historical Data, Backtesting)

I have been searching for historical options data for a while in the past times, I use shoonya and zerodha brokers, they don't provide data for expired contracts... I have come to know that ICICI Directs Breeze API povides data for expired contracts too... now the problem is that I have a total of 3 demat accounts as of now... now I don't want to have another demat account just for fetching the data and also AMC for ICICI Direct is ₹700 a year, I am student still... so if anyone using ICICI Direct or its API Services I would like to get the API Token, I am proficient with coding to fetch the required data and willing to share it as soon as I fetch it...
