const axios = require('axios');

const apiKey = "INSERT_YOUR_API_KEY_HERE";
const requestUrl = "";

const requestData = {
  "prompt": "a majestic landscape, vibrant and detailed, showcasing a blend of sunlight and shadows",
  "negative_prompt": "blurry, oversaturated, unrealistic",
  "samples": 1,
  "scheduler": "DDIM",
  "num_inference_steps": 30,
  "guidance_scale": 7.5,
  "seed": 123456789,
  "img_width": 1024,
  "img_height": 1024,
  "base64": true

async function generateImage() {
    try {
        const response = await, requestData, { headers: { 'x-api-key': apiKey } });
        console.log('Generated Image:',;
    } catch (error) {
        console.error('API Request Failed:', error);


This script demonstrates how to send a custom prompt to the SSD-1B API and receive an image in response. The flexibility in specifying parameters such as negative_prompt, num_inference_steps, and guidance_scale allows for a tailored image generation experience.
