promptrequiredstringDescribe the video. Required unless you supply an image or video input.
aspect_ratiooptionalstringFraming for text-to-video. Ignored when a first frame or reference sets the shape.
"16:9""4:3""1:1""3:4""9:16""adaptive"audiooptionalbooleanGenerate a synchronised soundtrack in the same pass. Does not change the price.
trueaudio_urloptionalstring (uri)Optional audio track to drive the video, including lip-sync.
durationoptionalintegerClip length, 2 to 30 seconds. Affects pricing (billed per rendered second). Use -1 to match the source when editing a video.
5Range: -1 - 30imageoptionalstring (uri)Start the video from this image (image-to-video).
last_frameoptionalstring (uri)Optional end frame. Use with First Frame to control the whole shot.
negative_promptoptionalstringContent to keep out of the video.
prompt_extendoptionalbooleanLet the model rewrite and enrich short prompts. Turning it off saves roughly 20-60 seconds but can reduce quality.
truereference_imagesoptionalstring[]Images whose subject, character or style the video should follow.
reference_videosoptionalstring[]Videos to guide motion or style, or the clip you want edited.
resolutionoptionalstringOutput resolution. Affects pricing: $0.068/s at 480P, $0.14/s at 720P, $0.28/s at 1080P.
"720P""480P""720P""1080P"seedoptionalintegerSeed for reproducible results.
watermarkoptionalbooleanAdd an "AI Generated" watermark.
falseResponse 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/wan3.0-video-primeSubmit — 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.
