How to use embeddings through API

[SebastiaanSG]

I'm using the api to generate images through python, but when I use the same generation data in the WebUI the images are way prettier. Then I found out it was because my (negative) embeddings aren't working.

I'm using:
negativeXL_D unaestheticXLv13

But they both aren't registering when I just use them as text:

payload = {
"prompt": input_prompt,
"steps": 50,
"cfg_scale": 7,
"negative prompt": "negativeXL_D unaestheticXLv13, text, words, letters, signature,"+additionalnegative,
"width": imgwidth,
"height": imgheight,
"sampler_index": "Euler a",
}

This is part of the function I'm using for this.

Can anyone help or explain to me how I can get the negative embeddings to start working,

Thanks in Advance!

This is the entire script, should it be helpful:

import json
import requests
import io
import base64
from PIL import Image, PngImagePlugin

def makeanimage(input_prompt, output_file, imgwidth=1024, imgheight=768, additionalnegative=""):
    url = "http://127.0.0.1:7860"

    payload = {
        "prompt": input_prompt,
        "steps": 50,
        "cfg_scale": 7,
        "negative prompt": "negativeXL_D unaestheticXLv13, text, words, letters, signature,"+additionalnegative,
        "width": imgwidth,
        "height": imgheight,
        "sampler_index": "Euler a",
        "denoising_strength": 0.7,
        "hr_scale": 1,
        "hr_upscaler": "Latent",
        "hr_second_pass_steps": 0,
        "hr_resize_x": 0,
        "hr_resize_y": 0,
    }

    response = requests.post(url=f'{url}/sdapi/v1/txt2img', json=payload)

    r = response.json()

    for i in r['images']:
        image = Image.open(io.BytesIO(base64.b64decode(i.split(",",1)[0])))

        png_payload = {
            "image": "data:image/png;base64," + i
        }
        response2 = requests.post(url=f'{url}/sdapi/v1/png-info', json=png_payload)

        pnginfo = PngImagePlugin.PngInfo()
        pnginfo.add_text("parameters", response2.json().get("info"))
        image.save(output_file, pnginfo=pnginfo)
        
if __name__ == "__main__":
    input_prompt = 'a really nice puppy'
    output_file = 'doggy.png'
    makeanimage(input_prompt, output_file)

It's not the embeddings. You forgot the underscore in negative_prompt, so you have no negative at all.

And it already has metadata (otherwise response2 would return nothing), so saving can be simplified.

    for i in r['images']:
        with open(output_file, 'wb') as f:
            f.write(base64.b64decode(i))

If you're only doing one image at a time, you don't need a loop.

    with open(output_file, 'wb') as f:
        f.write(base64.b64decode(r['images'][0]))
