  title: Civitai Blob Upload and Image-to-Image Generation
  summary: Upload a source image blob, run an img2img workflow against it, poll, and read the result.
  description: >-
    The image-to-image pattern on the Orchestration API. The workflow uploads a
    source image as a blob with built-in moderation, submits an imageGen step
    referencing that blob id as an input image, polls the workflow to completion,
    and reads the resulting output blob URL. The poll step loops on itself while
    the workflow is still processing. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
