4. Cost-Effective Alternative: LaoZhang.ai API Transit

For users requiring high-volume generation or cost optimization, consider using a reliable API transit service:

curl https://api.laozhang.ai/v1/images/generations \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $API_KEY" \
  -d '{
    "model": "gpt-image-1",
    "prompt": "Professional product photography of a modern smartphone",
    "quality": "medium",
    "size": "1024x1024"
  }'
