How this service works
Generate a QR code as SVG or PNG (base64 and data URI) for any text, URL, payment link, Wi-Fi or vCard, with error-correction level, scale and colors.
Output
A JSON object containing the QR code in base64-encoded form, a ready-to-use data URI (e.g. data:image/svg+xml;base64,...), the output format (svg or png), the QR version number, the module grid size, the error correction level applied, and the total byte size of the encoded image.
Example use cases
QR code for a restaurant menu
“Make me an SVG QR code for https://bistro-roma.com/menu with medium error correction and scale 6 — I want to print it on our table cards.”
Wi-Fi sharing QR code
“Generate a PNG QR code for the Wi-Fi credentials string 'WIFI:T:WPA;S:OfficeGuest;P:Welcome2024;;' with high error correction level h and scale 10 so guests can scan it easily.”
Branded payment link QR code
“Create a QR code in SVG format for my crypto payment link https://pay.example.com/invoice/42 — use dark color #1a1a2e and light color #e0e0ff, with error correction level q and scale 8.”
Technical details
Endpoint
POSThttps://api.vextorium.com/generar-qr-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a server-side QR code generated without client-side libraries, especially when you need SVG output for scalable embedding, a data URI ready for direct HTML use, or custom branded colors. Ideal for agents automating document generation, payment flows, contact sharing, or Wi-Fi onboarding where a scannable code is needed programmatically.
Side effects
- Missing required 'contenido' field returns validation error
- Invalid 'formato' value (not 'svg' or 'png') returns schema error
- Invalid 'correccion' value (not l/m/q/h) returns validation error
- Extremely long content string may exceed QR encoding capacity
- Non-JSON body type with JSON-required fields may cause parse error
