Request
account must be 22 digits (recipient CBU or CVU only).
Response
totalAmount is a decimal string.
statusIds carries the unique, non-empty, sorted statuses across all operations for the account:
1 (case filed), 2 (case confirmed as fraud), and 3 (genuine transaction). It is computed in the
same pass as the COUNT, so it adds no cost.
With availableCount=false, count, totalAmount, and statusIds are null: that mode stops at
the first match and never walks the operations.
Billing: free.
