Migrate from Stability AI API to Railwail

Before (Stability):

const form = new FormData();
form.append("prompt", "a cyberpunk city at sunset");
form.append("output_format", "webp");
form.append("aspect_ratio", "16:9");

const res = await fetch("https://api.stability.ai/v2beta/stable-image/generate/sd3", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.STABILITY_API_KEY}`,
    Accept: "image/*",
  },
  body: form,
});
const buf = Buffer.from(await res.arrayBuffer());

After (Railwail):

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.RAILWAIL_API_KEY,
  baseURL: "https://railwail.com/api/v1",
});

const res = await client.images.generate({
  model: "stable-diffusion-3-5-large",
  prompt: "a cyberpunk city at sunset",
  size: "1792x1024",
  response_format: "url",
});
console.log(res.data[0].url);

from openai import OpenAI

client = OpenAI(
    api_key=os.environ["RAILWAIL_API_KEY"],
    base_url="https://railwail.com/api/v1",
)

resp = client.images.generate(
    model="stable-diffusion-3-5-large",
    prompt="a cyberpunk city at sunset",
    size="1792x1024",
)
print(resp.data[0].url)

curl https://railwail.com/api/v1/images/generations \
  -H "Authorization: Bearer $RAILWAIL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "stable-diffusion-3-5-large",

  }'
