How to access image upscaling programatically?

[DjWarmonger]

Hello, I'm new to Stable Diffusion scripting.

I'd like to use Extras feature to batch-process a number images with my custom script, to avoid clicking through dozens of images. What is the best way to approach this? Is it accessible via API (didn't find such example), should I try to reuse sd_upscale.py script? Any other suggestions?

I just need someone to point me in the right direction.

Have you tried batch mode?

Otherwise, see /sdapi/v1/extra-single-image and /sdapi/v1/extra-batch-images in the API docs.

extra-single-image example:

import requests
import base64

url = "http://127.0.0.1:7860"

with open("input.png", "rb") as f:
    img = base64.b64encode(f.read()).decode('utf-8')

payload = {
    "resize_mode": 0,
    "upscaling_resize": 2,
    "upscaler_1": "ESRGAN_4x",
    "image": img
}

response = requests.post(url=f'{url}/sdapi/v1/extra-single-image', json=payload)
r = response.json()

with open("output.png", 'wb') as f:
    f.write(base64.b64decode(r['image']))

extra-batch-images example:

import requests
import base64
import glob

url = "http://127.0.0.1:7860"

images = []

for file in glob.glob('*.png'):
    with open(file, "rb") as f:
        images.append({"data": base64.b64encode(f.read()).decode('utf-8'), "name": file})

payload = {
    "resize_mode": 0,
    "upscaling_resize": 2,
    "upscaler_1": "ESRGAN_4x",
    "imageList": images
}

response = requests.post(url=f'{url}/sdapi/v1/extra-batch-images', json=payload)
r = response.json()

for n, i in enumerate(r["images"]):
    with open(f"output-{n}.png", "wb") as f:
        f.write(base64.b64decode(i))

Thanks, that was helpful. However, my API doesn't seem to contain these urls:

And I get 404, no suprise at this point.

I updated webui to lastest version when first posted this question, is there something wrong with my setup?

Okay, looks like I was wrong. Had to resinstall torch for CUDA and just update whole environment.

Thanks for help!
