What it can do

  • Qr Generate: Generate a fully branded QR code with explicit control over colors, module/finder shapes, logo, caption, and output format. Use this when the user already knows the design they want.
  • Qr Generate Ai: Generate a QR code where the QR Branding LLM picks colors and shapes from a natural-language prompt. Best for "make me a luxury gold dotted QR for a coffee brand" style requests.
  • Qr List Templates: List the 118 pre-designed QR templates (id, name, description, preview thumbnail URL). Filter by category if the user asks for a specific style.
