Raw names from tools/list. Only developers need these.

generate_qrGenerate a static QR code from any text/URL. Returns a PNG image (or SVG markup). Requires an OpenQR API key.
create_dynamic_qrCreate an editable (dynamic) QR code whose destination you can change later without reprinting. Requires an OpenQR API key.
update_dynamic_qrEdit a dynamic QR code: change its destination, label, custom short link (slug), tags or folder. Pass only the fields you want to change. Requires an OpenQR API key.
get_dynamic_qrGet the full details of one of your QR codes by id: destination, short link, label, type, tags, folder, status and created date. Requires an OpenQR API key.
get_scansGet scan statistics for a dynamic QR code. Requires an OpenQR API key.
list_dynamic_qrList your dynamic (editable) QR codes — id, short URL, destination, label and status. Requires an OpenQR API key.
delete_dynamic_qrPermanently delete a dynamic QR code. The short link stops working. Requires an OpenQR API key.
bulk_create_dynamic_qrCreate up to 200 dynamic QR codes at once. Requires an OpenQR API key.
list_foldersList your folders (id and name). Requires an OpenQR API key.
create_folderCreate a folder to organise codes. Requires an OpenQR API key.
delete_folderDelete a folder (its codes are un-filed, not deleted). Requires an OpenQR API key.
list_themesList your saved style themes (id, name) — apply one by passing its id or name as `theme` to generate/create/update tools. Requires an OpenQR API key.
create_themeSave a reusable style theme. `style` is a QR style object (fgColor, bgColor, dotType, cornerSquareType, etc.). Requires an OpenQR API key.
delete_themeDelete a saved theme. Codes already styled with it keep their look. Requires an OpenQR API key.
get_subdomainShow the branded subdomain on this account ({name}.oqr.to). Reports whether it is currently suspended — a suspended subdomain redirects to the plain short link instead of serving, which happens when a Pro plan lapses. Requires an OpenQR API key.
set_subdomainClaim or change the branded subdomain so codes also resolve at {name}.oqr.to. Pro only. Codes keep working on the plain short link either way, so changing this never breaks anything already printed. Requires an OpenQR API key.
clear_subdomainRelease the branded subdomain. Codes stay live on the plain short link; only the {name}.oqr.to form stops resolving. The name becomes claimable by someone else. Requires an OpenQR API key.
