How this service works
Generate a QR code for any text, URL, wallet address or payment link as SVG or PNG, returned inline as SVG markup and a base64 data URI ready for HTML or chat. Choose size, border and error correction. Use when a user needs a scannable code for a link, Wi-Fi, contact or crypto payment.
Output
Returns both inline SVG markup and a base64-encoded PNG data URI of the generated QR code, ready to embed directly in HTML, chat interfaces, or documents. The response includes the encoded data and the chosen format output so the agent can display or pass the QR code downstream without additional processing.
Example use cases
Crypto payment QR for checkout
“Generate a QR code for this Bitcoin wallet address bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh as an SVG with high error correction so I can put it on my invoice.”
Wi-Fi credentials sharing
“Make a QR code for my guest Wi-Fi — encode the text WIFI:T:WPA;S:GuestNetwork;P:password123;; — use PNG format, size 15, and a quiet-zone border of 4.”
Event landing page link
“I need a scannable QR code for https://events.mycompany.com/conf2025 to print on flyers — give me a large PNG at size 20 with H error correction so it still scans if part of it gets damaged.”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/util/qr?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, inline QR code with no additional processing — it returns both SVG markup and a base64 data URI ready to drop into HTML or a chat message without any image hosting step. Ideal for encoding URLs, crypto wallet addresses, payment links, Wi-Fi credentials, or plain text into a scannable code. Prefer it over client-side libraries when the agent cannot run JavaScript, or over image-generation APIs when you specifically need a QR code rather than a decorative image.
