The <code>GetAccountBalance</code> operation retrieves the Prepaid HITs balance in your Amazon Mechanical Turk account if you are a Prepaid Requester. Alternatively, this operation will retrieve the remaining available AWS Billing usage if you have enabled AWS Billing. Note: If you have enabled AWS Billing and still have a remaining Prepaid HITs balance, this balance can be viewed on the My Account page in the Requester console.
