Call this tool to draw many barcodes or QR codes at once from a list of rows, each with its own value and file name. Every row comes back as its own download link valid for one hour. Pro; the free tier does one code per call.
DiscoveredCall this tool to draw a linear barcode (code128, ean13, ean8, upca) as SVG, or PNG to out_path. A short EAN or UPC gets its check digit computed; a wrong one is refused, never redrawn. qr_create makes QR codes.
DiscoveredList the codes this server generated, newest first, with what each carried and where it went, plus how much of the free 20 a month is used. Filter by kind. It reads the register, not the files.
DiscoveredCall this tool for a SEPA payment QR from just an amount and reference: IBAN and name are read from the shared business profile, never asked for; pass invoice_id instead to take the amount from an invoice.
DiscoveredTurn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.
DiscoveredReport this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.
DiscoveredCall this tool to turn text or a URL into a QR code: SVG inline, or a PNG at a pixel size to out_path (Pro). Returns version, module grid and payload size. Free: 20 codes a month on this server.
DiscoveredCall this tool for an EPC069-12 payment QR a euro banking app can scan. Amount and reference are enough: the beneficiary IBAN and name default to the shared business profile, never asked for.
DiscoveredCall this tool to make a QR code that adds a contact when scanned (vCard 3.0). For your own card pass nothing: name, phone, email and address default to the shared business profile, never asked for.
DiscoveredCall this tool to make a QR code that joins a WiFi network when scanned: ssid, password and auth type, written to out_path or returned as SVG. Free: 20 codes a month. qr_create takes plain text or a URL.
