Free Stable Diffusion API?

[incomingflyingbrick]

I fount a free stable diffusion api from this site https://www.wizmodel.com/docs/sdApi is this the official API?

[wang-xiaowu]

execuse me，i got the result of the interface /sdapi/v1/txt2img，but how can i use it

[incomingflyingbrick]

Hi Xiaowu, You can use the code below to show the image. The image from SD is base64 encoded, so you have to decode it to bytes before you can use it or save it or show it. Let me know if you still have question

import requests
import json
from PIL import Image
from io import BytesIO
import base64

url = "https://api.wizmodel.com/sdapi/v1/txt2img"

payload = json.dumps({
  "prompt": "puppy dog running on grass",
  "steps": 50
})
headers = {
  'Content-Type': 'application/json',
  'Authorization': 'Bearer <YOUR_API_KEY>'
}

response = requests.request("POST", url, headers=headers, data=payload)

# Example base64 string (replace with your own)
base64_string = response.json()['images'][0]

# Decode the base64 string into bytes
image_data = base64.b64decode(base64_string)
image_bytes = BytesIO(image_data)

# Open and display the image using Pillow
image = Image.open(image_bytes)
image.show()

# Save the image to a local file
image.save("output_image.jpg")

I just reply to your question, please check it out on github.

hi, i try this, and the response.status_code is 502. Is something wrong?

Hi, Richiy, could you try again? It's working now. The server was done this morning. sorry about that.

Thanks now its working

[LeognidusW]

Hello! I'm a bit of a newbie, so I don't understand all the nuances. The Python code is working, but the C# code I need is not cooperating. I tried to make everything without asynchronous processing, as it was written in the documentation, could you help me figure it out? using System; using System.IO; using System.Net; using System.Text;

class Program { static void Main() { string url = "https://api.wizmodel.com/sdapi/v1/txt2img";

    // Подготовка данных для POST-запроса
    string postData = "{\"prompt\":\"puppy dog running on grass\",\"steps\":50}";
    byte[] data = Encoding.UTF8.GetBytes(postData);

    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.Method = "POST";
    request.ContentType = "application/json";
    request.Headers.Add("Authorization", "Bearer <MyApi c> >");

    using (Stream requestStream = request.GetRequestStream())
    {
        requestStream.Write(data, 0, data.Length);
    }

    using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
    using (Stream dataStream = response.GetResponseStream())
    using (StreamReader reader = new StreamReader(dataStream))
    {
        string responseText = reader.ReadToEnd();
        Console.WriteLine(responseText);
    }
}

} Of course, I enter my API key, but I keep getting this message. {"code":403,"msg":"Access denied: API-Key invalid","data":{}}

[incomingflyingbrick]

Hello Leognidus you can try the following C# code. It might work.

using System; using System.Net.Http; using System.Text; // for Encoding.UTF8 using System.Threading.Tasks; // for async Task using Newtonsoft.Json.Linq; // for JObject. Make sure to install the Newtonsoft.Json package.

class Program { private static readonly string ApiKey = "<YOUR_API_KEY>"; private const string Url = "https://api.wizmodel.com/sdapi/v1/txt2img";

static async Task Main()
{
    using var client = new HttpClient();

    // Prepare headers
    client.DefaultRequestHeaders.Add("Authorization", "Bearer " +

ApiKey); client.DefaultRequestHeaders.Add("Content-Type", "application/json");

    // Create payload
    var payload = new JObject
    {
        ["prompt"] = "puppy dog running on grass",
        ["steps"] = 100
    };

    var response = await client.PostAsync(Url, new

StringContent(payload.ToString(), Encoding.UTF8, "application/json"));

    if (response.IsSuccessStatusCode)
    {
        var jsonResponse = await response.Content.ReadAsStringAsync();
        Console.WriteLine(jsonResponse);
    }
    else
    {
        Console.WriteLine($"Error: {response.StatusCode}");
    }
}

}

Hey bro , how are you? This api works good? Are the images good? Can I run it on swift UI? this is gold

[incomingflyingbrick]

Hi SANTINO27, The API is working as expected. The image is good or not depends on what prompt you entered, the more detailed prompt the better. Yes, it doesn't work on Swift UI as long as you can send a simple HTTP POST request to the API :)

If you use jupyter you can do

`import base64 from IPython import display

js = response.json() base64_string = js['images'][0] image_data = base64.b64decode(base64_string)

display.display(display.Image(data=image_data))`

I noticed the api is giving the same image every time. Is there a seed option for this api?

"I noticed the api is giving the same image every time. Is there a seed option for this api?" We will try to add that

The api is giving same image for the same text

I added a seed, it should now output random picture everytime.

I added a seed, it should now output random picture everytime for you.

Good day! Denoising_strength stopped working in the img2img Wizmodel API. Now the API responds with some random images. Is there any way to make it work again?

I will take a look today

Hi Metim0l, I just tried the "denoising strength" parameter, it is working fine. Did you change your code recently? or You could upload your code here to see if there is anything wrong with it.

[incomingflyingbrick]

Btw this parameter's value is between 0 and 1 inclusive.

Hi Metim0l, May I know what application you are building so that you need to the "denoising strength" parameter, thz.

[valentin19]

Hi @incomingflyingbrick Have you changed the txt2img model recently? I have the impression that the images have lost quality..

[incomingflyingbrick]

Hi @valentin19 I noticed that. The refiner is not working properly. I am working on it right now , tring to fix it ASAP. Thank you.
