Tools & Capabilities Breakdown

QRX Tools (8)

generate_qr_code

Starts a new art QR code from a prompt and a link. Returns the code's id straight away.

vary_qr_code

Makes a new code from one of your codes with a change to its picture, such as "more trees". The new code has its own short link to the same destination; the original doesn't change.

get_qr_code

Gets a code's status, image and short link. Waits up to `wait` seconds (0 to 25, default 25) for a code that's still being painted.

list_qr_codes

Lists your codes, newest first, a page at a time (`limit` 1 to 100, default 20; pass `nextCursor` as `cursor`).

change_qr_code_destination

Points an existing link code at a new absolute http or https URL (on a paid plan). The printed code keeps working. Marked destructive, because it replaces the old destination.
