<p>
The <code>GetAccountBalance</code> operation retrieves the Prepaid HITs balance in your Amazon Mechanical Turk

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.
