# Change part of an image with Duaer

Duaer Edit sends the picture, and an optional mask, to `POST https://api.duaer.com/v1/images/generations`. The model is asked to change only what the instruction names.

## When to use

- Replace one object or region and leave the rest.
- On the canvas, use the Duaer Edit node. Change is required. Mask Binary Field is optional.

## Call

`POST https://api.duaer.com/v1/images/generations`

Header: `Authorization: Bearer <Duaer key>`

Without a mask, `image` is one data URL and the prompt is:

`Edit this image. Change only what this instruction names and leave the rest unchanged. Replace the cup with a glass of water.`

With a mask, `image` is an array of two data URLs. The second image marks the region. The prompt is:

`The first image is the picture. The second image marks the region to change: edit only that region. Leave every other part unchanged. Replace the cup with a glass of water.`

Also send `model`, `size` (`2560x1440`, `1440x2560`, or `2048x2048`), `response_format` `b64_json`, and `watermark`.
