promptrequiredstringRequired text describing scene, subject, motion and camera. Be specific about action and style.
aspect_ratiooptionalstringFrame shape such as 16:9, 9:16 or 1:1. Use 16:9 cinematic, 9:16 vertical social.
"16:9""16:9""1:1""21:9""3:4""4:3""9:16"durationoptionalstringClip length, either 5s or 10s. Use 5s for quick tests, 10s for storytelling.
"5s""5s""10s"end_frameoptionalstring (uri)Optional image URL for the final keyframe. Pair with start_frame for guided transitions.
resolutionoptionalstringOutput resolution: 360p, 540p, 720p or 1080p. Use 720p for balance, 1080p for hero shots.
"720p""360p""540p""720p""1080p"start_frameoptionalstring (uri)Optional image URL used as the first frame for image-to-video. Omit for pure text-to-video.
Response Type
Returns: Video
Asynchronous requests (v2)
Use Async for video, long-running (>~60s), or high-concurrency workloads; Sync is simplest for fast image & LLM calls. Async submits a request and you poll it to completion.
- 1
POST /v2/luma-ray-3-2Submit — returns request_id, status_url, response_url
- 2
GET /v2/requests/{id}/statusPoll — until COMPLETED or FAILED
- 3
GET /v2/requests/{id}Result — final response body
Status states
- A FAILED request is served as HTTP 422 — the body still carries the error detail.
- An unknown or expired request_id returns HTTP 404.
- Results are retained for 1 hour, then expire.
- Content / RAI blocks surface as FAILED, not a separate state.
- Track completion by polling the status endpoint.
