Inpainting is a conservation process where damaged, deteriorated, or missing parts of an artwork are filled in to present a complete image.

This is an asynchronous API, only the task_id will be returned. You should use the task_id to request the Task Result API at in new window to retrieve the image generation results.

Request header parameters

  • Content-TypestringRequired


  • AuthorizationstringRequired

    Bearer authentication format, for example: Bearer {{API Key}}.

I have no mask images, how to generate mask parameters in body?

You can use our playground to get the mask base64 info, please be aware that mask images should be the same resolution with input images, guidance here: Click Hereopen in new window API

I already have mask images, how to transfer mask images to base64?

You can use the following code to transfer mask images to base64.

import base64
# mask files path
filename_input = "mask_edited.png"

# read mask file
with open(filename_input, "rb") as f:
    base64_pic = base64.b64encode("utf-8")

# write mask file
with open("input.txt", "w") as f:

Start requesting for inpainting.

Please set the Content-Type header to application/json in your HTTP request to indicate that you are sending JSON data. Currently, only JSON format is supported.

"model_name":"realisticVisionV40_v40VAE-inpainting_81543.safetensors" in body represent inpainting models, which, can be accessed in API /v3/model with sd_name like %inpainting%.
