Use permanent keys only on a server. For signed-in browser calls, use the separate client route and quickstart.
POST /v1/qr accepts text or a structured payload, SVG/PNG, size128-1024 and error correction L/M/Q/H. Maximum QR text1600 UTF-8 bytes. Dense content may need a larger output or lower error correction.
POST /v1/payload builds URL, text, Wi-Fi, email, phone, SMS, vCard, geo and UPI data. UPI output encodes data only: it does not verify the payee or a payment.
