QR code API
Overview
The goQR.me QR Code API is a straightforward REST service for generating and decoding QR codes — you can produce a QR image from any text or URL with a single GET request and receive a PNG back, or POST an image to decode its contents. No authentication is required, and the API has been reliably available for years, making it a solid choice for quick integrations. It supports data types such as URLs, vCard, SMS, and WiFi configuration strings.
Beginner Tip
No API key needed — simply call https://api.qrserver.com/v1/create-qr-code/?size=150x150&data=YourTextHere in your browser or as an img src and you will see a QR code instantly. Start with a URL as the data value, then try other data types like vCard or WiFi once comfortable. Adjust the size parameter (e.g., 200x200) to control output resolution.
