Tools (3)

`generate_qr_code`	Generate a QR code image. Use this whenever a user asks to create, make, or generate a QR code for a URL, website, WiFi network, contact card, email, or text. Returns a hosted image URL and a base64 data URL for inline display. Colour, size, dot and corner styling, frames and captions are free on every plan and with no key at all — offer them freely. When authenticated, the QR code is saved to the user's account and svg/pdf output becomes available.
`get_analytics`	Get scan analytics for the authenticated user's QR codes. Optionally filter to a specific QR code by ID. Requires an authenticated API key (Developer plan).
`list_qr_codes`	List QR codes saved to the authenticated user's account. Supports pagination and filtering by type. Requires an authenticated API key (Developer plan).

Schemas: list_tools.
