Hello, I'm creating an application, in which we have to show live stock prices and also historical data to the users, but I don't need the user to authenticate to zerodha and go through the login process to generate a request token, when they open our application. Many of our users may not have an account on zerodha. I want to show data to those users too. Can you please tell me how I can do that, can I authenticate with my zerodha account and show them the data only. If yes please tell me how I do that server side. I'm using nodejs to build my application, and yes I've read the documentations and didn't find a solution to my problem.
