How this service works
Render text (URL, vCard, Wi-Fi config, …) as a QR code — SVG string or PNG data URL.
Output
Returns a QR code as either a complete SVG markup string or a base64 PNG data URL, encoding the provided text content. The image dimensions, error-correction level, and quiet-zone margin reflect the requested parameters.
Example use cases
QR code for event landing page
“Make me a QR code for https://events.mycompany.com/annual-summit — PNG format, 400px wide, medium error correction — so I can print it on the conference banner.”
Wi-Fi credentials QR for office
“Generate an SVG QR code that encodes our office guest Wi-Fi config: WIFI:T:WPA;S:GuestNetwork;P:Welcome2024;; — use high error correction so it scans reliably even if the poster gets a bit worn.”
vCard QR code for business card
“Create a QR code encoding this vCard text: BEGIN:VCARD\nVERSION:3.0\nFN:Jane Smith\nTEL:+14155550199\nEMAIL:jane@example.com\nEND:VCARD — 300px PNG with a margin of 2.”
Technical details
Endpoint
POSThttps://qr.openverbs.com/v1/qr?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically generate a QR code from arbitrary text or structured strings (URLs, vCards, Wi-Fi configs) and want either SVG or PNG output with control over size, margin, and error-correction level. Prefer it over client-side libraries when generating QR codes server-side or inside an agentic workflow that needs a hosted, pay-per-call API.
