# Image Eraser

This is an asynchronous API and only returns an asynchronous task\_id. You need to use the task\_id to call the task result query API to retrieve the image erasing result.

<Tip>
  This is an **asynchronous** API and will only return the task\_id of the asynchronous task. You should use this task\_id to request the [Get Task Result API](/en/docs/models/reference-get-async-task-result) to retrieve the generated result.
