# Run Luma Ray 3.2 (luma-ray-32)

`POST /models/luma-ray-32`

## Request

- Base URL: `https://api.hedra.com/v3`
- URL: `https://api.hedra.com/v3/models/luma-ray-32`
- Auth: one of:
  - API key in header `Authorization`
  - HTTP bearer

Cinematic motion with deliberate camera control, from a prompt.

Submits an asynchronous job and returns `202` with a job id. Fetch the result at `GET /v3/jobs/{job_id}` — each item in its `outputs[]` follows the `OutputItem` schema — or track progress via `GET /v3/jobs/{job_id}/status` / the SSE stream at `GET /v3/jobs/{job_id}/stream`.

## Headers

- `Idempotency-Key` string

## Request body

- SubmitBodyLumaRay32
  - `input` InputLumaRay32, required: Model-specific inputs for `luma-ray-32`.
    - `num_outputs` 1: Number of outputs generated per job. Only 1 is supported.
    - `prompt` string, required: Generation prompt. At most 6000 characters.
    - `aspect_ratio` '3:4' | '4:3' | '1:1' | '9:16' | '16:9' | '21:9', required: Output aspect ratio.
    - `resolution` '540p' | '720p' | '1080p', required: Output resolution.
    - `duration_ms` 5000 | 10000, required: Duration in ms.
  - `webhook` string, uri, nullable: URL to receive a signed completion webhook.

## Response `202`

Accepted. The job runs asynchronously; poll `status_url` / `result_url` from the ack.

- SubmitResponse
  - `job_id` string, required: This job's id — server-issued, and opaque.
  - `model` string, required: The resolved model id this job runs on.
  - `status` 'IN_QUEUE' | 'IN_PROGRESS' | 'COMPLETED' | 'FAILED', required: The four states a job can be in.
  - `status_url` string, required: Path of this job's status monitor: poll GET /v3/jobs/{job_id}/status for status, progress, and the estimated completion time.
  - `result_url` string, required: Path of the job resource itself: GET /v3/jobs/{job_id} returns the result envelope, including the outputs once it completes. Also the value of this response's `Location` header.
  - `estimated_completion_at` string, date-time, nullable: ISO-8601 instant this job is estimated to finish, as of this response. Null when no estimate is available yet, and when the job has already finished. The estimate can change while the job runs: poll `GET /v3/jobs/{job_id}/status` for the current one.
