Subfork Examples

OpenAI Video Generation Job

This experimental graph submits an OpenAI video generation job and polls its status using generic Subfork job primitives.

Before running it, add a graph-scoped secret named OPENAI_API_KEY in Graph Settings > Execution Profile.

The graph shape is:

Text Value + optional URL Input -> JSON Template -> HTTP Submit Job -> JSON Path -> Status URL -> HTTP Poll Job -> Content URL -> HTTP Request -> Video Preview

The composite surface should expose:

For an uploaded reference image, add an Image Asset node and connect its url output to image_url. Provider URL handoff requires a publicly reachable Subfork deployment; subfork.localhost cannot be fetched by OpenAI.

The Status URL node constructs /v1/videos/{id} from the submitted job ID. After the poll node reaches completed, Video content URL constructs /v1/videos/{id}/content, and Fetch video content retrieves the authenticated video bytes as a video/* media payload for the Video Preview panel.

The request body uses JSON Template optional keys:

{
  "input_reference?": {
    "image_url?": ""
  }
}

The trailing ? means “omit this key when the rendered value is empty, null, an empty array, or an empty object.” That prevents invalid payloads such as "image_url": "" when the graph is used text-only.

Expected outputs:
