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.
