## Create Task
Generate video through Wan 3.0. The high-speed model uses
model=wan/3-0-video-prime;
After submission, use the unified query endpoint to check task progress and retrieve results
::: tip[]
For production use, we recommend providing the `callBackUrl` parameter
so your service can receive completion notifications instead of polling
for task status.
:::
:::tip
Billed seconds = output duration + total duration of reference videos.
With duration = -1, billing follows the duration the model chooses. For
current prices, see [kie.ai/pricing](https://kie.ai/pricing).

properties:
prompt:
type: string
maxLength: 20000
description: >-
Text prompt. Chinese and English are supported. Up to
20,000 characters. Required for text-to-video; for other
modes, it is recommended to provide it together with
media. In reference mode, use Image1/Video1/Audio1 to
reference the provided materials.
examples:

A kitten running across a rooftop under the moonlight,
neon lights flickering in the distance, cinematic
quality, with smooth camera movement.
first_frame_url:
type: string
format: uri
description: >-
URL of the first-frame image. Up to 1 image, used
strictly as the first frame of the video. Used for
first-frame-to-video or first-and-last-frame-to-video
generation. Cannot be provided together with
`reference_*_urls`.
Formats: JPEG/JPG, PNG (transparency not supported),
BMP, WEBP; each side [240, 8000] px; aspect ratio ≤ 8:1;
≤ 20MB.
last_frame_url:
type: string

items:
type: string
format: uri
description: >-
Reference images for all-purpose reference mode. Up to
10 images. Correspond to Image1, Image2, and so on in
the prompt according to array order. Same specifications

maxItems: 5
items:
type: string
format: uri
description: >-
Reference videos for all-purpose reference mode. Up to 5
videos. Each video must be 1–15s, with a combined
