https://api.segmind.com/v1/minimax-h3-max-turboParameters
promptrequiredstringDescribe the scene, subject, motion and camera. Used for both text-to-video and image-to-video.
aspect_ratiooptionalstringOutput aspect ratio for text-to-video. Ignored when an Image is provided (the output follows the image).
"16:9""21:9""16:9""4:3""1:1""3:4""9:16"durationoptionalintegerLength of the generated video, 5 to 15 seconds. Billed per second of output.
5Range: 5 - 15imageoptionalstring (uri)Optional first frame. When set, the video starts from this image and takes its aspect ratio (image-to-video). Leave empty for text-to-video.
last_frame_imageoptionalstring (uri)Optional end frame, used together with Image: the model interpolates from the first frame to this one.
prompt_expansion_modeoptionalstringHow much effort to spend rewriting the prompt before generation. 'balanced' returns in about a second; 'quality' spends up to ~30s on a richer prompt.
"balanced""balanced""quality"resolutionoptionalstringOutput resolution. 480P is the cheaper tier; 768P is the default quality tier.
"768P""480P""768P"seedoptionalintegerSeed for reproducible generation. -1 for random.
-1Range: -1 - 999999999999999Response 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/minimax-h3-max-turboSubmit — 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.
Common Error Codes
