# gc_get_topic

> Get a policy topic

One curated policy topic (e.g. artificial-intelligence, water-quality): its place in the taxonomy (parent, child topics) and how to see activity classified under it. Topics are the cross-agency View — follow one to monitor a policy area everywhere it appears.

## Input

| Parameter | Type | Description |
| --- | --- | --- |
| idRequired | string | Topic slug (from gc_search). |

## Annotations

```
{
  "readOnlyHint": true,
  "idempotentHint": true,
  "openWorldHint": false
}
```

## Examples

### One policy topic

  "id": "air-quality"
}

        }
      ]
    },
    "activity_via": "gc_list_activity (scope: {type: \"topic\", id: \"air-quality\"}) — rulemaking, press, grants, and legislative activity classified under this topic (child topics roll up)."
  },
