Detailed Option Data Access - Sources

Hi,

How do I get spreadsheet data on most active stock Put and Call options with data like OI, Greeks, price, Volatility etc? . I currently use trendlyne data but I am scared they will stop publishing this. Is there a way to subscribe to this directly from NSE? This is not available in Sensibull and I find very little results on google.

In sensibull , only option chains can be pulled up for the stock. This means that once you enter a specific stock, there is a chance there will be no liquid contracts for that expiry. However, In the trendlyne you can screen by all available contracts

As a follow up question, how do these companies like trendlyne get their data? It must be from NSE right? If i want personalized data, should I approach NSE directly?
