Wan 2.6 - Text to 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.

High-quality video generation from text descriptions powered by Wan's advanced AI model

Overview

Generate videos directly from text descriptions using the Wan 2.6 Text to Video model. This model creates dynamic video content from natural language prompts without requiring any input images. Output: a 16:9 video with generated audio (portrait output is not available).

Usage Tips

INFO

• Supports both Chinese and English prompts
• Maximum prompt length: 5,000 characters
• Minimum prompt length: 1 character
• Choose appropriate duration and resolution based on your needs

Query Task Status

After submitting a task, use the unified query endpoint to check progress and retrieve results:

• Get Task Details — Learn how to query task status and retrieve generation results

TIP

For production use, we recommend using the callBackUrl parameter to receive automatic notifications when generation completes, rather than polling the status endpoint.

Request Parameters

Body (application/json)

Parameter	Type	Required	Description
model	string	Yes	The model name to use for generation. Required field. - Must be wan/2-6-text-to-video for this endpoint Default："wan/2-6-text-to-video"。 Allowed values：wan/2-6-text-to-video。 示例：wan/2-6-text-to-video。
callBackUrl	string	No	The URL to receive generation task completion updates. Optional but recommended for production use. - System will POST task status and results to this URL when generation completes - Callback includes generated content URLs and task information - Your callback endpoint should accept POST requests with JSON payload containing results - Alternatively, use the Get Task Details endpoint to poll task status - To ensure callback security, see Webhook Verification Guide for signature verification implementation 示例：https://your-domain.com/api/callback。
input	object	No	Input parameters for the generation task
input.prompt	string	Yes	Text prompts for video generation. Supports both Chinese and English, with a minimum of 1 characters and a maximum of 5,000 characters. (Max length: 5000 characters) 示例：In a hyperrealistic ASMR video, a hand uses a knitted knife to slowly slice a burger made entirely of knitted wool. The satisfyingly crisp cut reveals a detailed cross-section of knitted meat, lettuce, and tomato slices. Captured in a close-up with a shallow depth of field, the scene is set against a stark, matte black surface. Cinematic lighting makes the surreal yarn textures shine with clear reflections. The focus is on the deliberate, satisfying motion and the unique, tactile materials.。
input.duration	string	No	The duration of the generated video in seconds Default："5"。 Allowed values：5 / 10 / 15。 示例：5。
input.resolution	string	No	Output resolution: 720p or 1080p. Set this field explicitly. Allowed values：720p / 1080p。 示例：1080p。
input.multi_shots	boolean	No	The multi shots parameter controls the shot composition style during AI video generation, determining whether the generated video is a single continuous shot or multiple shots with transitions. Default：false。 示例：false。
input.nsfw_checker	boolean	No	Defaults to false. When false, no additional content filtering is applied and results are returned directly by the model.
