    Every operationId below exists verbatim in the published Vyond OpenAPI at
    https://api.vyond.com/doc/openapi.json. Note that steps 2 and 4 each spend
    account credits and Vyond accepts no Idempotency-Key, so a fork of this
    workflow must not blind-retry them.

    required: [feature, generationType]
    properties:
      feature:
        type: string

        enum: [vyondGo, aiAvatar]
      vyondGoParams:
        type: object
        description: Required when generationType is vyondGo.
      aiAvatarParams:
        type: object
        description: Required when generationType is aiAvatar.
      exportCategory:
        type: string

    outputs:
      parameters: $response.body
  - stepId: create-generation
    description: >-
      Create the content generation. SPENDS CREDITS — no idempotency key is
      accepted, so do not retry this step on a timeout.
    operationId: ContentGenerationV2Controller.createGeneration
    requestBody:
      contentType: application/json
      payload:

  - stepId: poll-generation
    description: >-
      Poll until status resolves. Back off exponentially — 429 is declared with no
      published limit and no Retry-After header.
    operationId: ContentGenerationV2Controller.getGeneration
    parameters:

      generationStatus: $response.body#/status
  - stepId: export-video
    description: >-
      Export the generated video. SPENDS CREDITS — returns 402 Payment Required
      when the account is exhausted, and no endpoint reads the credit balance.
      completionCriteria is required for SCORM categories.

  - stepId: get-download-url
    description: >-
      Retrieve the download URL. It expires at expireAt — fetch the bytes
      immediately rather than persisting the URL.
