    }
  }'

Prediction Flow

1. Check model GET https://api.eachlabs.ai/v1/model?slug=<slug> — validates the model exists and returns the request_schema with exact input parameters. Always do this before creating a prediction to ensure correct inputs.
2. POST https://api.eachlabs.ai/v1/prediction with model slug, version "0.0.1", and input matching the schema
3. Poll GET https://api.eachlabs.ai/v1/prediction/{id} until status is "success" or "failed"
4. Extract the output image URL from the response

Tips for Best Results

• Use high-quality source images with clear, well-lit faces
• The source face image should be a clear frontal or near-frontal portrait
• Matching lighting conditions between source and target produces more natural results
• Specify "seamless blending" and "natural skin tone" in prompts
• For the target image, faces should be clearly visible and not heavily occluded
