The same shape on every platform. A field a platform does not have is null, and meta.unavailable says why. Use fields= to keep only what you need.

| Field | Type | Description |
|---|---|---|
| `rank` | integer | Position on the board, 1 is the top. |
| `name` | string | The topic or search term. |
| `heat` | number \| null | The heat score the platform shows; scales differ by platform. |
| `url` | string \| null | Link to the topic page, if there is one. |
