# List Tag Keys

List all tag keys set on any sandbox in the org, with per-key counts
of tagged sandboxes and distinct values. Useful for building
group-by pickers without querying the full tag set.

<Note>
  **Preview:** Usage and tag APIs are new. Endpoints, response fields,
  and SDK method names may change before GA; temporary inaccuracies or
  rough edges are possible while the surface settles.
</Note>

<ResponseExample>
  ```json 200 theme={null}
  {
    "keys": [
      { "key": "team", "sandboxCount": 17, "valueCount": 4 },
      { "key": "env",  "sandboxCount": 23, "valueCount": 3 }
    ]
  }
  ```
</ResponseExample>

<Note>
  Tag keys on torn-down sandboxes are retained so historical drilldowns
  keep resolving. As a result `sandboxCount` may include sandboxes
  that are no longer active.
