How to Build a Ai Art Generator

// Using Stability AI's SDXL API
  async function generateArt(prompt, style, aspectRatio) {
  const styleMap = {
    'oil-painting': 'oil painting, impasto brushstrokes, canvas texture',
    'watercolor': 'watercolor painting, soft washes, paper texture',
    'digital-art': 'digital art, sharp details, vibrant colors',
    'pencil-sketch': 'pencil sketch, graphite, cross-hatching, paper'
  };
  const fullPrompt = `${prompt}, ${styleMap[style] || ''}`;

  const response = await fetch('https://api.stability.ai/v1/generation/stable-diffusion-xl-1024-v1-0/text-to-image', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.STABILITY_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      text_prompts: [{ text: fullPrompt, weight: 1 }],
      cfg_scale: 7, steps: 30, samples: 1,
      width: aspectRatio === '16:9' ? 1344 : 1024,
      height: aspectRatio === '16:9' ? 768 : 1024
    })
  });
  const data = await response.json();
  return `data:image/png;base64,${data.artifacts[0].base64}`;
