How this service works
QR code generation returning clean scalable SVG: any text/URL up to 1800 chars, selectable error-correction level (L/M/Q/H).
Output
Returns a JSON object containing an SVG string of the rendered QR code, the effective error correction level used (e.g. 'M'), and the module count (e.g. 29) indicating QR code density.
Example use cases
WiFi password sharing at events
“Create a QR code from this WiFi password: 'EventGuest2024!@#' with maximum error correction so guests can scan it reliably even in crowded rooms.”
Product packaging with contact details
“Make me a QR code that encodes our business contact info: 'John's Bakery | (555) 123-4567 | john@bakery.local' with medium-high error correction for printing on packaging.”
Digital menu distribution for restaurants
“Generate a QR code pointing to 'https://myrestaurant.com/menu' with high error correction so customers can scan it from any angle or distance without issues.”
Technical details
Endpoint
GEThttps://api.aventtech.com/generate/qr?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically generate a QR code as an SVG (scalable, resolution-independent) from arbitrary text or a URL, especially when error correction tuning (L/M/Q/H) is needed. Prefer over raster-image QR generators when scalable vector output is required.
Side effects
- Text exceeds 1800 characters — returns an error indicating input too long
- Invalid error correction level value (not L/M/Q/H) — may default to M or return validation error
- Missing required 'text' query parameter — returns 400-style error
- Payment not provided or insufficient — returns 402 Payment Required
