  - string
  - string — Legacy alias prefix; accepted on read, never emitted on write.
- `region` string
- `availability_zone` string
- `accelerator` string
- `form_factor` string
- `rdma_type` string
- `num_accelerators` integer
- `num_vcpus` integer

  - `object` 'list', required
  - `cursor` string
  - `has_more` boolean, required
  - `data` InstanceSkuAvailability[], required
    - `object` 'instance_sku_availability', required
    - `instance_sku` InstanceSkuSummary, required — A summary of an instance SKU - its `id` and human-recognizable `alias` - embedded on resources that reference a SKU.
      - `object` 'instance_sku', required

      - `alias` string, required
    - `schedule` ScheduleEntry[], required — Node count over time, as a list of `[start_at, end_at)` time ranges. Example: 5 nodes from t=0 to t=3600 is `[{"start_at": 0, "end_at": 3600, "node_count": 5}]`. `start_at` and `end_at` must be 60-second aligned, `node_count` must be non-negative. On non-final entries, `end_at` may be omitted (inferred from the next entry's `start_at`); gaps fill with `node_count: 0`.
      - `start_at` integer, required — Unix timestamp.
      - `end_at` integer — Unix timestamp.
      - `node_count` integer, required
