How to Use the QR Code Generator API — Free REST + MCP Server

#qrcode #api #webdev #mcp

Need to generate QR codes on the fly? Skip the bloated npm packages. This API generates QR codes as PNG, SVG, or base64 — supports URLs, vCards, WiFi configs, emails, and phone numbers.

Try It Right Now

Generate a PNG QR code in your browser:

https://api.lazy-mac.com/qr-code/api/v1/generate?data=https://api.lazy-mac.com

Or get it as base64 for embedding:

curl -s "https://api.lazy-mac.com/qr-code/api/v1/generate/base64?data=Hello%20World" | jq

Response:

{
  "base64": "data:image/png;base64,iVBORw0KGgoAAAANS..."
}

All Endpoints
