How this service works
Generate QR codes from text, URLs, or any string data. Returns clean SVG output with a base64 data URL for easy embedding. Pure computation — no external API calls.
Output
Returns an object with: 'svg' (the full SVG markup string), 'dataUrl' (a data:image/svg+xml;base64,... string ready to drop into an <img> src), 'ascii' (Unicode block-character rendering), and 'moduleCount' (number of QR modules per side). SVG and dataUrl are populated when format is 'svg'; ascii is populated when format is 'ascii'.
Example use cases
Embed scannable code in email campaigns
“Create a QR code for our seasonal sale landing page at https://promo.example.com/summer2024 in SVG format so I can drop it directly into our HTML email template.”
Generate Wi-Fi access credentials instantly
“Make a QR code from this Wi-Fi connection string: WIFI:T:WPA;S:GuestNetwork;P:TempPass123!; use high error correction so it scans reliably even if partially obscured.”
Produce contact sharing code for events
“Turn this vCard contact into a QR code: BEGIN:VCARD\nFN:Sarah Chen\nTEL:+1-555-0123\nEMAIL:sarah@company.com\nEND:VCARD—I need the ASCII version so I can display it in terminal logs.”
Technical details
Endpoint
POSThttps://qr.withzero.ai/run?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pure-computation, serverless QR code with no external API dependencies, especially when you want an embeddable SVG/base64 output or a Unicode ASCII preview. Ideal for agents generating QR codes on the fly to embed in HTML, emails, or documents without needing a third-party QR service.
Side effects
- Input 'data' field is empty or missing — returns validation error
- Input string exceeds 4296 characters — returns error for data too long
- Size out of range (below 32 or above 2048) — validation error
- Invalid enum value for format or errorCorrection — validation error
