# AI Image Watermark Remove API

> Remove visible text and watermarks from image content.

## Overview

`image-watermark-remove` is an AI image processing endpoint for removing visible text, logos, and watermarks from a source image.
It accepts one image URL as input and returns an asynchronous task for processing.

## Parameter Notes

* `img_urls`: Source image URLs. Exactly one image URL is supported for each task.

## Usage Example

```json theme={null}
{
  "model": "image-watermark-remove",
  "callback_url": "https://your-domain.com/api/callback",
  "input": {
    "img_urls": [
      "https://example.com/input-image.jpg"
    ]
  }
}
```

## Query Task Status

After submitting a task, use the unified query endpoint to check progress and retrieve results:

</Card>

<Tip>
  For production use, we recommend using the `callback_url` parameter to receive automatic notifications when generation completes, rather than polling the status endpoint.
