Wan - 2.6-flash-image-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.

Transform images into dynamic videos 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.

TIP

Enabling audio costs more. For current prices, see ai.modelfold.online/pricing.

Request Parameters ​

Body (application/json) ​

ParameterTypeRequiredDescription
modelstringYesThe model name to use for generation. Required field.
- Must be wan/2-6-flash-image-to-video for this endpoint Default:"wan/2-6-flash-image-to-video"。 Allowed values:wan/2-6-flash-image-to-video。 示例:wan/2-6-flash-image-to-video。
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 示例:https://your-domain.com/api/callback。
inputobjectNoInput parameters for the generation task
  input.promptstringYesText prompts for video generation. Supports Chinese and English, 2–1,500 characters. 示例:Anthopmopric fox singing a Christmas song at the rubbish dump in the rain.。

  input.multi_shotsbooleanNoThe 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. (Boolean value (true/false)) 示例:false。
