LinQR

The LinQR API generates QR‑code images for many data types—phone numbers, SMS messages, plain text, Wi‑Fi credentials, cryptocurrency payment details, email, geographic coordinates, contact cards, and arbitrary payloads—and also supports batch QR‑code creation. In addition, it provides endpoints to list, retrieve, upload, and delete the resulting image files.
