QR Code Generator API

Generate QR codes from text, URLs, WiFi credentials, vCards, email links, and SMS messages. Every endpoint returns a ready-to-use image as base64 and a data URL, with full control over colors, size, error correction, and an optional logo overlay. Use it in event tools, venue WiFi flows, ecommerce apps, CMS plugins, internal dashboards, and marketing automation.
