Wan 2.7 Image

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.

Based on wan/2-7-image, image generation and editing are achieved.

Query Task Status

After submitting the task, you can check the progress of the task and obtain the generated results through the unified query endpoint:

Get Task Details — Learn how to check the task status and obtain the generated results

TIP

In the production environment, it is recommended to use the "callBackUrl" parameter to receive the automatic notification upon completion of the generation, rather than polling the status endpoint.

Parameter	Type	Required	Description
`model`	`string`	Yes	Model name for generation tasks. This endpoint currently uses `wan/2-7-image`. Default：`"wan/2-7-image"`。 Allowed values：`wan/2-7-image`。示例：`wan/2-7-image`。
`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`	Yes	Input parameters for the generation task
`input.prompt`	`string`	Yes	Prompt for image generation or editing.
