What is the QR Code API?
The Helix QR Code API generates QR codes from any text, URL, or structured payload in milliseconds. It returns PNG, JPEG, SVG, or base64-encoded images that you can embed in your application, print on physical products, or display on screens — all with one HTTP request.
How it works
- 1Send a GET or POST request with your data (text, URL, vCard, WiFi config) to /generate.
- 2Customize size, colors (foreground/background), error correction level (L/M/Q/H), and output format.
- 3The API returns the QR code as raw image bytes — no SDK, no rendering library, no fonts to install.
- 4Built-in TTL caching means identical requests return instantly without re-rendering.
- 5Use it on signup forms, payment links, restaurant menus, event tickets, WiFi sharing — anywhere a scannable code is needed.
Endpoints
2 REST endpoints, all returning consistent JSON.

Real use cases from production deployments.
Payment Links That Convert
Generate QR codes for Stripe, PayPal, Razorpay, UPI, or any payment URL. Customers scan with their phone camera and complete checkout in 3 taps. Industry data shows QR-based mobile payments convert 27% higher than typed URLs.
WiFi Sharing for Cafés and Hotels
Encode your network's SSID and password as `WIFI:S:MyNetwork;T:WPA;P:mypass;;` — guests scan and connect automatically. Print once, no more whiteboards with passwords.
vCard Contacts and Digital Business Cards
Embed full contact details (name, phone, email, company, URL) in a vCard QR. One scan adds you to a recipient's address book — perfect for trade shows, conferences, and B2B sales teams.
Event Tickets and Inventory
Generate unique QR codes per ticket or SKU. Scanners at the gate or warehouse decode instantly, even on low-end Android devices. Add error correction level H to survive crumpled paper and bad lighting.
Marketing Campaigns with Attribution
Pair QR codes with our URL Shortener API to track per-channel scans — see which billboard, flyer, or social post drove conversion. No analytics SDK required, just a redirect with logging.
