  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "model": "stable-diffusion-3-5-medium",
    "version": "0.0.1",
    "input": {
      "prompt": "a majestic eagle soaring over snow-capped mountains, photorealistic, golden hour lighting",
      "aspect_ratio": "16:9",
      "cfg": 5,
      "steps": 40,
      "output_format": "webp"
    }
  }'

Parameters

Parameter	Type	Default	Description
aspect_ratio	string	1:1	Output aspect ratio. enum: 1:1, 16:9, 21:9, 3:2, 2:3, 4:5, 5:4, 3:4, 4:3, 9:16, 9:21
cfg	number	5	Guidance scale - how similar the output should be to the prompt
image	string	-	Input image for image-to-image mode
output_format	string	webp	Output format. enum: webp, jpg, png
output_quality	integer	90	Quality of output images, from 0 to 100
prompt	string	-	Text prompt for image generation
prompt_strength	number	0.85	Prompt strength when using image-to-image. 1.0 is full destruction of input
seed	integer	-	Set a seed for reproducibility. Random by default
steps	integer	40	Number of steps to run the sampler for
