Best Practices

For Realistic Results

• High-quality source images: Use well-lit photos where eyes are clearly visible
• Front-facing portraits: Best results with eyes looking toward the camera
• Describe iris details: Mention if you want specific patterns, flecks, or gradients
• Natural lighting reference: Mention the lighting style for consistent reflections

For Fantasy Effects

• Specify the aesthetic: Vampire, alien, anime, supernatural, etc.
• Describe intensity: Subtle glow vs. bright luminescence
• Include character context: Helps AI match the overall style

Prompt Tips

1. Be specific about shade: "Ice blue" vs. "ocean blue" vs. "navy blue"
2. Mention blending: Ask for natural transitions at iris edges
3. Request iris texture: Preserve or modify the natural patterns
4. Consider lighting: Specify if you want reflections maintained

Mode Selection

Mode	Best For	Speed	Quality
max	Final photos, professional use, detailed effects	Slower	Highest
eco	Quick previews, batch variations, testing colors	Faster	Good

Multi-Turn Creative Iteration

Use session_id to refine eye color changes:

# Initial change
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Change the eye color to blue"}],
    "model": "eachsense/beta",
    "stream": true,
    "image_urls": ["https://example.com/portrait.jpg"],
    "session_id": "eye-edit-project"
  }'

# Refine the result
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Make the blue more intense and add a slight ring of darker blue around the edge of the iris"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "eye-edit-project"
  }'

# Add special effect
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Now add a subtle glow effect to make the eyes look magical"}],
    "model": "eachsense/beta",

Error Handling

Error	Cause	Solution
Failed to create prediction: HTTP 422	Insufficient balance	Top up at eachlabs.ai
No eyes detected	Face not visible or eyes closed	Use a photo with clearly visible open eyes
Unnatural blending	Poor source image quality	Use higher resolution, well-lit photos
Timeout	Complex generation	Set client timeout to minimum 10 minutes
