Wan 3.0 - Video

This page is generated from the upstream official OpenAPI documentation. Endpoints, parameters and examples match the official docs; brand and API domain are replaced with ModelFold.

Endpoint

POST /jobs/createTask

Full URL: https://ai.modelfold.online/v1/jobs/createTask

Authentication: every request must include the Authorization: Bearer <API_KEY> header.

Create Task

Generate video through Wan 3.0. The standard model uses the parameter "model=wan/3-0-video".

Get Task Details — 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 ai.modelfold.online/pricing.

Request Parameters

Body (application/json)

Parameter	Type	Required	Description
`model`	`string`	Yes	wan/3-0-video is the standard model. The name of the model used to generate videos. This field is required. - This endpoint must be `wan/3-0-video` Allowed values：`wan/3-0-video`。示例：`wan/3-0-video`。
`callBackUrl`	`string`	No	The callback URL for task completion notifications. This parameter is optional. If provided, the system will send a POST request to this URL when the task is completed, regardless of whether it succeeds or fails. If not provided, no callback notification will be sent.
`input`	`object`	Yes	Parameters for Wan 3.0 video generation.
`input.prompt`	`string`	No	Text prompt, supporting both Chinese and English. Up to 20,000 characters. Required for text-to-video generation; for other modes, it is recommended to provide it together with media. In reference mode, use Image1/Video1/Audio1 to reference the provided media. 示例：`A kitten running across a rooftop under the moonlight, neon lights flickering in the distance, cinematic quality, with smooth camera movement.`。
`input.first_frame_url`	`string`	No	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 / 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.
`input.last_frame_url`	`string`	No	URL of the last-frame image. Use together with first_frame_url. Same format limits as first_frame_url.
`input.reference_image_urls`	`array<string>`	No	Reference images for the all-purpose reference mode, with up to 10 images. Correspond to Image1, Image2, … in the prompt according to array order. Specifications are the same as `first_frame_url`. Cannot be provided together with the first-frame/last-frame parameters.
`input.reference_video_urls`	`array<string>`	No	Reference videos for the all-purpose reference mode, with up to 5 clips. Each clip must be 1–15 seconds, with a total duration ≤ 15 seconds. Correspond to Video1, Video2, … according to array order. Formats: mp4, mov; each side [240, 4096] px; aspect ratio ≤ 8:1; each file ≤ 100MB. There is an additional constraint on the output side: the input video duration + `duration` must not exceed 30 seconds.
`input.reference_audio_urls`	`array<string>`	No	Reference audio for the all-purpose reference mode, with up to 5 clips. Each clip must be 1–15 seconds, with a total duration ≤ 15 seconds. Correspond to Audio1, Audio2, … according to array order. Formats: wav, mp3; ≤ 15MB. Reference audio can be used as the only media input; pairing it with a reference image or video usually gives better results.
`input.reference_file_urls`	`array<string>`	No	File-to-video generation. Up to 1 file. Cannot be provided together with `reference_link_urls`, or with the first-frame/last-frame parameters. Formats: docx/doc/xlsx/xls/pptx/ppt/pdf/txt/key/pages/numbers/md; ≤ 100MB; pdf/docx/ppt/key/pages, etc. ≤ 50 pages.
`input.reference_link_urls`	`array<string>`	No	Link-to-video generation. Up to 1 publicly accessible webpage that does not require login. Cannot be provided together with `reference_file_urls`, or with the first-frame/last-frame parameters.
`input.resolution`	`string`	No	Output resolution. Default: 1080P. Default：`"1080P"`。 Allowed values：`480P` / `720P` / `1080P`。示例：`1080P`。
`input.aspect_ratio`	`string`	No	Output aspect ratio. `adaptive` (default) automatically selects the ratio based on the input media and intent. Default：`"adaptive"`。 Allowed values：`adaptive` / `16:9` / `4:3` / `1:1` / `3:4` / `9:16`。示例：`adaptive`。
`input.duration`	`integer`	No	Output video duration in seconds. Default: 5. Without video input, the range is [2, 30]. With reference videos: input video duration + output duration ≤ 30. Pass `-1` to use an intelligent duration determined by the model. Default：`5`。示例：`5`。
`input.audio`	`boolean`	No	Whether the output video includes an audio track. Default: true. Default：`true`。示例：`true`。
`input.seed`	`integer`	No	Random seed used to reproduce results. If omitted, a random seed will be used.
`input.nsfw_checker`	`boolean`	No	Defaults to false. When false, no additional content filtering is applied and results are returned directly by the model.
