Quick Start

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": "Create a stylized QR code for https://mywebsite.com with a modern tech aesthetic"}],
    "model": "eachsense/beta",
    "stream": true,
    "mode": "max"
  }'

QR Code Design Considerations

Element	Best Practice	Impact on Scannability
Error Correction	High (30%) recommended for artistic QR	Allows more design freedom
Logo Size	Max 30% of QR area	Larger logos reduce reliability
Color Contrast	Dark modules on light background	Essential for scanning
Quiet Zone	Maintain white border	Required for reliable scanning
Module Style	Rounded, dots, or custom shapes	Minimal impact if consistent

Best Practices

Design Guidelines

• Contrast is Key: Maintain strong contrast between modules and background
• Test Scannability: Always verify the generated QR code scans properly
• Error Correction Level: Higher levels allow more artistic freedom
• Quiet Zone: Preserve white space around the QR code
• Module Clarity: Keep modules distinct even with artistic styling

Color Guidelines

• Dark on Light: Traditional contrast works best
• Avoid Red/Green: May cause issues for colorblind users
• Consistent Styling: Apply effects uniformly across all modules
• Background Contrast: Ensure sufficient contrast with placement surface

Mode Selection

Ask your users before generating:

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

Mode	Best For	Speed	Quality
max	Final production QR codes, print materials, branded assets	Slower	Highest
eco	Quick previews, concept testing, multiple variations	Faster	Good

Multi-Turn Creative Iteration

Use session_id to iterate on QR code designs:

# Initial QR code design
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": "Create a stylized QR code for https://mybrand.com with a modern tech aesthetic"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "qr-design-project"
  }'

# Refine the design
