Add `/inventory/attributes/{attribute_name}/values` endpoint for retrieving unique attribute values.

Currently, to get all unique values for a specific device attribute, users must:

1. Fetch all devices via `/api/management/v1/inventory/devices`

2. Process the response client-side to extract and deduplicate values

**Proposed Solution:**  
Add a new API endpoint: `GET /api/management/v1/inventory/attributes/{attribute_name}/values`

Response Example:

```json
{
  "attribute_name": "device_type",
  "values": ["raspberry-pi", "esp32", "imx6", "beaglebone"],
  "total_count": 4
}

```

This would enable `SELECT DISTINCT column` - like queries.

Hi @martingrzzler,

Thanks for reaching out. I definitely can see the value in such an endpoint, because as you say, it reduces API calls. This is obviously not something which can be decided by you and me here on Mender Hub, but I’m forwarding it to product planning and drop a follow-up here once I know more.

Hi @martingrzzler,

Feedback from the backend team is that you should be able to achieve this with the endpoint documented at [Mender API docs](https://docs.mender.io/api/?http#management-api-device-inventory-filters-and-search-get-filterable-attributes).

Thank you @TheYoctoJester ,

If I’m not mistaken, this endpoint only returns `name`, `scope`, and the `count` for each attribute but not the unique values for that attribute.

Cheers!

Martin

Hi @martingrzzler,

Indeed, thats possible. I have raised the feature request back to the product team.
