    "stream": true,
    "session_id": "batch-watermark-001",
    "mode": "eco",
    "image_urls": ["https://example.com/video-1.mp4", "https://example.com/company-logo.png"]

Best Practices

Adding Watermarks

• Opacity: Use 20-40% opacity for subtle branding, 50-70% for visible protection
• Size: Keep logo watermarks at 5-15% of video width for professional look
• Position: Bottom corners are standard; avoid center unless for drafts/previews
• Contrast: Add shadow or outline to watermarks for visibility on varied backgrounds
• Consistency: Use the same watermark settings across all your content

Removing Watermarks

• Quality: Higher quality source videos yield better removal results
• Simple backgrounds: Watermarks over simple/uniform areas are easier to remove
• Multiple watermarks: Specify all watermark locations for comprehensive removal
• Legal use: Only remove watermarks from content you own or have licensed

Mode Selection

Ask your users before generating:

"Do you want fast & cheap, or high quality?"

Multi-Turn Watermark Iteration

Use session_id to refine watermark placement:

# Initial watermark
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": "Add my logo watermark to this video in the bottom right corner"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "watermark-project-001",
    "image_urls": ["https://example.com/my-video.mp4", "https://example.com/logo.png"]
  }'

# Adjust based on feedback
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": "The watermark is too large and too opaque. Make it 50% smaller and reduce opacity to 25%"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "watermark-project-001"
  }'

# Final adjustment
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": "Move it slightly more to the center to avoid the video controls overlay area"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "watermark-project-001"
  }'
