# CPF — CUIT in-list

> Cheap CUIT membership check against CPF with optional mode, counts, and accumulated amounts.

## Request

```http theme={null}
GET /api/integration-services/ar_gueno_cpf_service/cuits/:cuit/in-list?mode=both&availableCount=true
```

| Query            | Rule                                                                                                           |
| ---------------- | -------------------------------------------------------------------------------------------------------------- |
| `mode`           | `recipient` \| `initiator` \| `both` (default)                                                                 |
| `availableCount` | `true` (default) = COUNT + amounts; `false` = EXISTS only (`count` / role counts / amounts are `null`, faster) |

## Response

```json theme={null}
{
  "success": true,
  "data": {
    "cuit": "30703088534",
    "mode": "both",
    "inList": true,
    "count": 14,
    "asRecipientCount": 2,
    "asInitiatorCount": 12,
    "totalAmount": "1015000.00",
    "asRecipientTotalAmount": "35000.00",
    "asInitiatorTotalAmount": "980000.00"
  }
}
```

Amounts are decimal strings (same currency as the CPF corpus). With `availableCount=false`, `count`, role counts, and all `*Amount` fields are `null`.

**Billing:** free.
