Where can I see my account balance

From 99Stack Cloud Docs

Your account balance can be viewed after logging in to the control panel (dash.99stack.com) or via a GET API request to `/v1.2/account/info`

A live estimation of the due date for your next payment, based on current usage can be found together with the information about your current balance using both methods above. Pay close attention to that timestamp as late payments can lead to data loss.
