How this service works
Use when you need a qr code generator for a URL, text, Wi-Fi or payment link as an SVG image. Do not use for reading or decoding an existing QR code, logos, colored codes or PNG output. Returns JSON with a QR code for your text or URL as SVG markup and an SVG data URL, with error correction level and border options, generated by the uqr library for 0.004 USDC per call. Typical response time 500 ms (p95). Category: Media.
Output
Returns a JSON object containing the full SVG markup of the QR code, an SVG data URL suitable for embedding in HTML or CSS, the QR version number, the number of modules, the error correction level used, and the byte size of the encoded data.
Example use cases
QR code for a product landing page
“Create a QR code for https://myshop.com/product/shoes — use medium error correction and a 2-module border, and give me the SVG so I can embed it in the packaging design.”
Wi-Fi sharing QR code
“Generate an SVG QR code for this Wi-Fi credentials string: WIFI:T:WPA;S:HomeNetwork;P:mypassword123;; — use high error correction so it scans easily even if the printout is a bit crumpled.”
Payment link QR for invoice
“Make a QR code for this payment link https://pay.example.com/invoice/INV-2024-0042 with Q-level error correction and a border of 4, I want the SVG markup to put on a printed invoice.”
