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

​
Application Process

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

Finally, go to the Tasks API page Wan 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 Wan Tasks API can be used to query the results of the Wan Videos Generation API. For information on how to use the Wan Videos Generation API, please refer to the document Wan Videos Generation API. We will take a task ID returned by the Wan Videos Generation API as an example to demonstrate how to use this API. Suppose we have a task ID: a4bca552-d964-46a1-8ff7-fd922f916582, 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 key to call 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/wan/tasks' \
-H 'accept: application/json' \
-H 'authorization: Bearer {token}' \
-H 'content-type: application/json' \
-d '{
  "id": "a4bca552-d964-46a1-8ff7-fd922f916582",
  "action": "retrieve"
}'

​
Python

import requests

url = "https://api.acedata.cloud/wan/tasks"

headers = {
    "accept": "application/json",
    "authorization": "Bearer {token}",
    "content-type": "application/json"
}

payload = {
    "id": "a4bca552-d964-46a1-8ff7-fd922f916582",
    "action": "retrieve"
}

response = requests.post(url, json=payload, headers=headers)
print(response.text)

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 video task generated, used to uniquely identify this video generation task.
  • request: The request information in the video task.
  • response: The return information in the video task.

​
Batch Query Operation

This is for querying the details of 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.
