With the Kite Connect Personal app, it's not possible to access real-time or historical market data.
If you have created multiple apps, please ensure that you're using the API key and access token for the Connect app (paid version), rather than the Personal app (free version). This issue typically arises when the credentials from the Personal app are used instead, or your Kite Connect subscription has expired.
