## Request

```

`account` must be 22 digits (recipient CBU or CVU only).

| Query            | Rule                                                                                                  |
| ---------------- | ----------------------------------------------------------------------------------------------------- |
| `availableCount` | `true` (default) = COUNT + amount; `false` = EXISTS only (`count` / `totalAmount` are `null`, faster) |

## Response

```json theme={null}
{
  "success": true,
  "data": {
    "account": "0000151500039430130126",
    "accountType": "cvu",
    "inList": true,
    "count": 4,
    "totalAmount": "125000.50"
  }
}
```

`totalAmount` is a decimal string. With `availableCount=false`, `count` and `totalAmount` are `null`.
