  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "model": "sdxl-lightning-4step",
    "version": "0.0.1",
    "input": {
      "prompt": "A superhero smiling, bright colors, dynamic pose",
      "width": 1024,
      "height": 1024,
      "num_inference_steps": 4,
      "scheduler": "K_EULER"
    }
  }'

Parameters

Parameter	Type	Default	Description
disable_safety_checker	boolean	true	Disable safety checker for generated images
