How this service works
QR code. Send text or a URL (up to 1,000 characters); returns a QR code as PNG or SVG, base64 in JSON, with its size, version and error-correction level, at the scale and quiet zone you choose. Use to put a link or payment request on a page, label or PDF. Plain codes only, no logos or colours. Typical response under 200 ms. Failed calls are not charged.
Output
A JSON object containing the QR code image as a base64-encoded string (PNG or SVG), along with metadata including the QR version, image dimensions, and the error-correction level used. Typical response time is under 200 ms.
Example use cases
QR code for product packaging label
“Make a QR code for https://acme.com/product/widget-pro that I can print on a packaging label — PNG, scale 12, border 4, and use Q error correction so it still scans if part gets smudged.”
Payment link QR code on invoice PDF
“I need a QR code for my payment link https://pay.stripe.com/inv/abc123 to drop into a PDF invoice — SVG format, scale 8, standard 4-module quiet zone, M error correction is fine.”
WiFi password QR code for office signage
“Create a QR code that encodes WIFI:T:WPA;S:OfficeGuest;P:Welcome2024;; — PNG, scale 15, border 4, use H error correction so it works even if the sign gets a bit worn.”
