Generate and decode / read QR code graphics.
About QR code
The QR code API, provided via api.qrserver.com and operated by goQR.me (Foundata GmbH), allows developers to generate and decode QR code graphics over HTTP. QR codes can be created by calling a URL with parameters such as size and data, and the service supports colored QR codes by specifying background and foreground colors, provided sufficient contrast is maintained between light and dark modules.
Output formats include professional print-ready vector graphics such as EPS and SVG, in addition to standard image formats. The API also supports reading/scanning QR codes via internet requests, and communication is encrypted via HTTPS.
The service is aimed at developers building their own QR code generation or reading functionality into other applications. goQR.me also operates QR Server, a separate marketing platform for QR code campaign management with editable QR codes.
