List of dataset items

- object
  - `data` DatasetItem[], required
    - `id` string
    - `dataset_id` string
    - `input` object[]: Messages replayed verbatim as the generation's input
      - `role` string, required
      - `content` string, required: Message content — a string, or AI SDK content parts
    - `expected_output` string, nullable
    - `metadata` MetadataBag: Caller-owned annotations on a resource, stored as the object they were written as: the types a value was written with are the types a read returns, so a filter can ask an ordering question about a number. Unlike other body fields, keys are stored and returned verbatim in the casing supplied — they are not converted between snake_case and camelCase. No key is reserved, and that is the point: every piece of state the platform owns lives in its own typed column, so nothing written here reaches platform state. The platform never reads the bag — it is not an IAM context, not a policy input and not part of a prompt — which is what separates it from a tag bag.
    - `source_generation_id` string, nullable: The generation this item was curated from. A curated item is a deliberate fixture: erasing the source generation neither deletes nor mutates it.
    - `created_at` string, date-time
    - `updated_at` string, date-time
  - `total` integer, required
  - `limit` integer, required
  - `offset` integer, required
