The main function of the SeeDance Tasks API is to query the execution status of tasks by inputting the task ID generated by the SeeDance Video Generation API. This document will provide detailed integration instructions for the SeeDance Tasks API, helping you easily integrate and fully utilize the powerful features of this API. With the SeeDance Tasks API, you can easily query the execution status of tasks from the SeeDance Video Generation API.

​
Application Process

To use the SeeDance Tasks API, you first need to apply for the corresponding service on the application page SeeDance Video Generation API, and then copy the task ID from the SeeDance Video Generation API, as shown in the image below:

Finally, go to the Tasks API page SeeDance Tasks API to apply for the corresponding service. After entering the page, click the “Acquire” button, as shown in the image below: Application Page If you are not logged in or registered, you will be automatically redirected to the login page inviting you to register and log in. After logging in or registering, you will be automatically returned to the current page. There is a free quota available for first-time applicants, allowing you to use this API for free.

​
Request Example

The SeeDance Tasks API can be used to query the results of the SeeDance Video Generation API. For information on how to use the SeeDance Video Generation API, please refer to the document SeeDance Video Generation API. We will take a task ID returned by the SeeDance Video Generation API as an example to demonstrate how to use this API. Suppose we have a task ID: 20068983-0cc9-4c6a-aeb6-9c6a3c668be0, and we will demonstrate how to pass in a task ID.

Setting Request Headers and Request Body

Request Headers include:
  • accept: Specifies that the response should be in JSON format, set to application/json.
  • authorization: The API key for calling the API, which can be selected directly after application.
Request Body includes:
  • id: The uploaded task ID.
  • action: The operation method for the task.
Set as shown in the image below:

​
Code Example

You can see that various language codes have been automatically generated on the right side of the page, as shown in the image below:

Some code examples are as follows:

​
CURL

curl -X POST 'https://api.acedata.cloud/seedance/tasks' \
-H 'accept: application/json' \
-H 'authorization: Bearer {token}' \
-H 'content-type: application/json' \
-d '{
  "id": "a6e0d456-189b-4c78-9232-2fe72166ab39",
  "action": "retrieve"
}'

​
Response Example

After a successful request, the API will return the details of the task here. For example: 
{
    "_id": "69480c5cff2676299c7b351d",
    "id": "9462ca25-468b-45a5-9e75-6f516dedcc80",

        }
    }
}
The returned result contains multiple fields, with the request field being the request body when the task was initiated, and the response field being the response body returned after the task is completed. The field descriptions are as follows.
  • id: The ID of the generated task, used to uniquely identify this generation task.
  • request: The request information in the task query.
  • response: The return information in the task query.

​
Batch Query Operation

This is for querying task details for multiple task IDs, and unlike the above, the action needs to be selected as retrieve_batch. Request Body includes:
  • ids: An array of uploaded task IDs.
  • action: The operation method for the task.
Set as shown in the image below:
