WiFi QR Code API

Generate WiFi QR codes that connect a phone to a network on scan — no typing the password. Use it for guest networks, offices, cafes, venues, vacation rentals, events, and onboarding flows. Output is a ready-to-use PNG or SVG image.

This endpoint is part of the QR Code Generator API.

`size_px`	`integer` or `null`	Rendered width in pixels for PNG; `null` for SVG.

Tips

Open networks: set encryption to nopass and omit password.
Hidden networks: set hidden to true so the device knows to search for a non-broadcasting SSID.
Special characters: the API escapes ;, ,, :, and \ in the SSID and password for you — send them as-is.
Print large: for posters, raise box_size or use output: "svg" so the code stays crisp at any size.
