| `after` | query | no | Cursor from `list_metadata.after`. |

## Response

`200 OK` with `data[]` (version metadata) and `list_metadata`.

```json
{"data": [{"version": 4, "snapshot_sha256": "3f1c…", "source": "publish", "rolled_back_from": null,
           "actor_type": "api_key", "actor_id": "key_01jb…", "published_at": "2026-10-05T09:31:00Z"}],

```
