qr

Generate and read QR codes in one API for agents and automation. Generate a QR code from any text or URL as a PNG (base64) or scalable SVG, with configurable error-correction level, quiet-zone margin, and scale. Decode reads the embedded payload from an uploaded image (multipart, base64, or public HTTPS URL), returning the decoded data, QR version, and corner coordinates. Image downloads are SSRF-protected (no private IPs, no redirects); no shell access.
