How this service works
Generate a QR code as PNG or SVG from any text or URL. Pick the size, error-correction level (L/M/Q/H) and foreground/background colours; a 4-module quiet zone is always included so it scans reliably. Returns the raw image bytes. No logo overlay (compositing is out of scope).
Output
Raw image bytes of the generated QR code in the requested format (PNG or SVG), ready for display or embedding. The image always includes a 4-module quiet zone for reliable scanning.
Example use cases
Example prompt
“Generate a 512px PNG QR code for https://myshop.example.com using high error-correction (H level), with a dark blue foreground (#003366) on a white background.”

Endpoint
POSThttps://402utils.com/v1/qrWhen to prefer
Use this endpoint when you need to programmatically generate a QR code image (PNG or SVG) from a URL or text string, especially when you need fine-grained control over error-correction level, image size, and custom colors. It is a simple, stateless, pay-per-call endpoint with no logo overlay support — ideal for automation pipelines that need reliable, scannable QR codes without dependencies on a hosted dashboard.
