not sure if i am doing it correctly but when I run the example.py with the correct username and password i am getting this:

Kuna API request error: 400, message='Bad Request', url=URL('https://server.kunasystems.com/api/v1/account/auth/')

During handling of the above exception, another exception occurred:

Are you sure the username and password are correct? Username is an email address and password is a string.
