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.

Content generation using bytedance/v1-pro-image-to-video

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 bytedance/v1-pro-image-to-video for this endpoint Default:"bytedance/v1-pro-image-to-video"。 Allowed values:bytedance/v1-pro-image-to-video。 示例:bytedance/v1-pro-image-to-video。
callBackUrlstringNoThe URL to receive generation task completion updates. Optional but recommended for production use.
