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

​
Application Process

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

Finally, go to the Flux Tasks API page Flux 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 Flux Tasks API can be used to query the results of the Flux Images Generation API. For information on how to use the Flux Images Generation API, please refer to the documentation Flux Images Generation API. We will use a task ID returned by the Flux Images Generation API service as an example to demonstrate how to use this API. Suppose we have a task ID: 2db0168c-2373-4367-8d9a-9dc778802e8a, and we will demonstrate how to pass in a task ID.

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