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-2-7-video	Use the wan-2-7-video 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	-	720p, 1080p	Resolution
duration	number	No	5	min 0 / max 15	-	text/image: integer 2–15 s; video edit: duration=0 or integer 2–10 s
aspect_ratio	select	No	16:9	-	16:9, 9:16, 1:1, 4:3, 3:4	Text-to-video and video-editing runs use this directly. Image-to-video currently follows the uploaded frame geometry instead of exposing a separate aspect-ratio switch.
negative_prompt	text	No	-	-	-	prompt ≤ 5000; negative_prompt ≤ 500
prompt_extend	select	No	true	-	true, false	Controls whether the model rewrites your prompt before generation. Keep it on for convenience, or turn it off when you already have a very precise prompt.
watermark	select	No	false	-	false, true	Watermark
audio_setting	select	No	auto	-	auto, origin	Controls how audio is handled in the video-edit path. Auto lets the model decide, while Keep original tries to preserve the source video's audio.
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.
