    "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?"

Mode	Best For	Speed	Quality
max	Final output, professional content, watermark removal	Slower	Highest
eco	Batch processing, drafts, testing placement	Faster	Good

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"
  }'

Error Handling

Error	Cause	Solution
Failed to create prediction: HTTP 422	Insufficient balance	Top up at eachlabs.ai
Content policy violation	Prohibited content	Ensure content complies with terms of service
Timeout	Long video processing	Set client timeout to minimum 10 minutes
Invalid video format	Unsupported format	Convert to MP4, MOV, or WebM
Watermark not detected	AI cannot locate watermark	Specify watermark location more precisely
