# `RuleBodyProprietary` type

The body of a PROPRIETARY rule: the built-in check the rule runs.

A PROPRIETARY rule carries no query or function of its own — the check ships with the platform — so naming the check is the whole body.

## Fields

| Field Name | Description |
|---|---|
| `check` - [`ProprietaryCheckId!`](https://wartiva.com/api-docs/types/proprietary-check-id.html) | The built-in check this rule runs. |

## Used by

- [`RuleBody`](https://wartiva.com/api-docs/types/rule-body.html) union: A polymorphic body for a rule type.
- [`RuleType`](https://wartiva.com/api-docs/types/rule-type.html) enum: Describes how a rule gathers the input its function evaluates.

## Example

### Example

```json
{"check": "ANTIVIRUS_STATE_STALE"}

```
