Request contract

Send the model id at the top level. Model-specific controls belong in params.

Key	Type	Required	Default	Description
model	string	Yes	wan-2-2-a14b-turbo	Use the wan-2-2-a14b-turbo API model id.
prompt	string	Yes	-	Maximum 5000 characters for this model.
params	object	No	-	Model-specific parameter object. Use the rows below for allowed keys.
client_request_id	string	No	-	Optional client-side id for tracing requests in your system.

Model parameters

Key	Type	Required	Default	Range	Options	Description
resolution	select	No	720p	-	480p, 580p, 720p	Text and image input support 480p or 720p (40 or 80 credits for 5 seconds). Image plus audio also supports 580p; its 480p / 580p / 720p rates are 12 / 18 / 24 credits per output second.
aspect_ratio	select	No	16:9	-	16:9, 9:16	This stays available only in text-to-video because the current public image and image-plus-audio-driven endpoints do not expose a stable `aspect_ratio` field.
enable_prompt_expansion	select	No	false	-	false, true	Turn this on when you want the upstream service to expand a rough text prompt before generation. It stays limited to text and image runs.
seed	number	No	-	min 0 / max 2147483647	-	Leave it empty for a new random result each time. Reusing the same integer makes it easier to reproduce or fine-tune a previous result. It stays closer only when the prompt and other key settings also remain similar, and it is not a guaranteed 1:1 match.
acceleration	select	No	none	-	none, regular	A lighter acceleration control that remains limited to the public text and image modes.
num_frames	number	No	80	min 40 / max 120 / step 4	-	Image-plus-audio-driven only. Valid values are 40 to 120, and the number must be divisible by 4. A typical starting point is 80.
frames_per_second	number	No	16	min 4 / max 60 / step 1	-	Image-plus-audio-driven only. Valid values are 4 to 60. Higher FPS usually feels smoother, but also raises generation pressure.
negative_prompt	text	No	-	-	-	Image-plus-audio-driven only. Use it to describe motion failures, unwanted artifacts, or visual elements you want to avoid.
num_inference_steps	number	No	27	min 2 / max 40 / step 1	-	Image-plus-audio-driven only. Valid values are 2 to 40. Higher steps can improve quality, but they also increase runtime.
guidance_scale	number	No	3.5	min 1 / max 10 / step 0.1	-	Image-plus-audio-driven only. Valid values are 1 to 10. Higher values follow the prompt more closely, but can also make motion feel stiffer.
shift	number	No	5	min 1 / max 10 / step 0.1	-	Image-plus-audio-driven only. Valid values are 1 to 10. It changes the temporal offset feel of the generation, so it is safest to start near the default.
enable_safety_checker	select	No	true	-	true, false	Image-plus-audio-driven only. Turn it on to run safety checks before generation, or turn it off when you need less filtering and accept the trade-off.

Upload policy

Upload reference files first, then place the returned URL and duration token inside params.referenceMediaItems.

Reference rule

Reference media: Upload up to 2 assets. Text mode needs none, image-to-video uses 1 image, and the image-plus-audio-driven path uses 1 image plus 1 audio clip.

Max files

Accepted file kinds

image, audio

Duration token

Video and audio references should carry durationToken from /api/v1/files when duration verification is required.

kind	Max size	MIME types
image	10 MB	image/jpeg, image/png, image/webp
audio	10 MB	audio/mpeg, audio/mp4, audio/wav, audio/x-wav, audio/aac, audio/ogg, audio/flac, audio/x-ms-wma
