Wan - 2.2 A14B Text to Video Turbo ​

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

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) ​

ParameterTypeRequiredDescription
modelstringYesThe model name to use for generation. Required field.
- Must be wan/2-2-a14b-text-to-video-turbo for this endpoint Default:"wan/2-2-a14b-text-to-video-turbo"。 Allowed values:wan/2-2-a14b-text-to-video-turbo。 示例:wan/2-2-a14b-text-to-video-turbo。
callBackUrlstringNoThe 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。
inputobjectNoInput parameters for the generation task
  input.promptstringYesThe text prompt to guide video generation. (Max length: 5000 characters) 示例:Drone shot, fast traversal, starting inside a cracked, frosty circular pipe. The camera bursts upward through the pipe to reveal a vast polar landscape bathed in golden sunrise light. Workers in orange suits operate steaming machinery. The camera tilts up, revealing the scene from the perspective of a rising hot air balloon. It continues ascending into a glowing sky, the balloon trailing steam and displaying the letters "ModelFold AI" as it rises into breathtaking polar majesty.。
  input.resolutionstringNoResolution of the generated video (480p or 720p). Default value: "720p" Default:"720p"。 Allowed values:480p / 720p。 示例:720p。
  input.aspect_ratiostringNoAspect ratio of the generated video (16:9 or 9:16). Default value: "16:9" Default:"16:9"。 Allowed values:16:9 / 9:16。 示例:16:9。
  input.enable_prompt_expansionbooleanNoWhether to enable prompt expansion. This will use a large language model to expand the prompt with additional details while maintaining the original meaning. (Boolean value (true/false)) 示例:false。
  input.seednumberNoOptional. Omit for a random seed.
  input.accelerationstringNoAcceleration level to use. The more acceleration, the faster the generation, but with lower quality. The recommended value is 'none'. Default value: "none" Default:"none"。 Allowed values:none / regular。 示例:none。
  input.nsfw_checkerbooleanNoDefaults to false. When false, no additional content filtering is applied and results are returned directly by the model.
