  title: MobileAPI Browse Devices by Type and Year
  summary: List devices of a given type, then narrow to a launch year, branching when a slice is empty.
  description: >-
    Supports faceted browsing of the catalog. The workflow lists devices of a
    requested type (phone, tablet, laptop, wearable, or other), then narrows to
    a specific launch year. Both endpoints return 204 when a facet has no
    matches, so the flow branches explicitly: an empty year slice ends the
    workflow gracefully rather than treating the empty response as a match.
    Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.

  summary: List devices by type, then by launch year, branching on empty 204 slices.
  description: >-
    Lists devices of the requested type, then lists devices for the requested
    launch year. When the year slice returns 204 (no matches) the workflow ends
    on the empty branch; otherwise it surfaces the first matching device.
  inputs:
    type: object
    required:
    - apiKey
    - type
    - year
    properties:
      apiKey:
        type: string
        description: MobileAPI key, sent in the Authorization header as 'Token <apiKey>'.
      type:
        type: string
        description: Device type facet to browse.
        enum:
        - phone
        - tablet
        - laptop
        - wearable
        - other
      year:
        type: integer
        description: Four-digit launch year to narrow to (e.g. 2023).
      page:
        type: integer
        description: Page number for both listings (default 1, 50 per page).
  steps:
  - stepId: listByType
    description: >-
      List the first page of devices of the requested type. A 204 here would
      mean no devices exist for the type; a 200 returns the paginated slice.

    description: >-
      List devices launched in the requested year. The endpoint returns 200
      with a slice when matches exist and 204 when the year has no devices.
