🟢 Nur lesen🟡 Schreiben🔴 Löschen⚪ Unbekannt
🟢license_status

Report 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.

Eingabe-Schema

{
  "type": "object",
  "properties": {},
  "$schema": "http://json-schema.org/draft-07/schema#"
}
⚪license_activate(key)

Turn 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.

🟡qr_create(text, error_correction, size, margin, format, ...)

Call 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.

🟡barcode_create(symbology, value, module_width, height, text, ...)

Call 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.
