Generate QR Code

Generate a QR code for any string and return a base64-encoded PNG. Configurable size and error correction level.

GET

https://requiems.xyz/v1/technology/qr/base64

Parámetros

Nombre	Tipo	Obligatorio	Descripción
data	`string`	Obligatorio	The string to encode into the QR code (URL, text, or any string).
size	`integer`	Opcional	Output image size in pixels (width and height). Min 50, max 1000. Defaults to 256.
recovery	`string`	Opcional	Error correction level: low, medium, high, or highest. Higher levels allow more of the QR code to be damaged while still scanning.
