## Properties

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `object` | string | Yes | Type of object is always `networkAvailabilityTileset`. |
| `expiresAt` | string | Yes | Time when the signed `urlTemplate` expires. Fetch the tilesets again before then. |
| `layers` | object[] | Yes | The layers inside the tiles, ordered from the broadest coverage to the fastest technology. |
| `maxZoom` | integer | Yes | The highest zoom level the tiles cover. Beyond it, map libraries scale up existing tiles instead of fetching new ones. |
| `minZoom` | integer | Yes | The lowest zoom level the tiles cover. |
| `urlTemplate` | string | Yes | Tile URL template in the standard XYZ format. Pass it to a map library unchanged: the library fills in the `{z}`, `{x}` and `{y}` placeholders. |
