Get MBS Item
This endpoint retrieves detailed information about a specific MBS item using its item number.
#### 🎨 **How It Works**
- Sources data from MBS and enriches it with RebateRight details.
- Includes **MBS notes** and additional insights including the **limitation period**, specifying how often an item can be claimed within a given timeframe (e.g., **not more than three times in a 12-month period**).
If the item number is unknown, the API returns **404** with a plain-text body — see the **`404`** example.
