promptrequiredstringDescriptive text to shape your video. Use detailed prompts for vivid storytelling.
durationoptionalintegerChoose video length. Short durations suit demos; longer ones for detailed scenes.
66810generate_audiooptionalbooleanEnable audio generation for an immersive experience. Use for interactive or detailed presentations.
trueimageoptionalstring (uri)Optional image input for video generation. Use high-res JPEG or PNG for enhanced outputs.
resolutionoptionalstringSelect video resolution. 1080p for web use, 4k for cinematic quality.
"1080p""1080p""2k""4k"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/ltx-2-proSubmit — 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.
