How this service works
Encode text or a URL as a QR code: PNG (base64 and a data URL) or SVG, with the size and error correction level you choose.
Output
A JSON object containing the image format (png or svg), the output size in pixels, the file size in bytes, the raw base64-encoded PNG string (png_base64), and a ready-to-use data URL (data_url) for inline embedding. SVG responses return the SVG markup instead of base64.
Example use cases
QR code for a landing page
“Make me a QR code for https://mystore.com/sale as a 300-pixel PNG — I want to print it on flyers so use high error correction level H.”
Embed QR code in an email template
“Generate an SVG QR code for the text 'Join our webinar at zoom.us/j/123456789' at 256 pixels with medium error correction so I can drop it straight into an HTML email.”
Wi-Fi credentials as QR code
“Create a QR code that encodes 'WIFI:T:WPA;S:GuestNetwork;P:welcome2024;;' — give it to me as a PNG data URL at 512 pixels with Q-level error correction so guests can scan it off a laminated card.”

Endpoint
GEThttps://q7w9tnp09rjt5ccj.68r.lambda-web.us-east-1.on.aws/v1/qr?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a programmatic, on-demand QR code as an embeddable image (data URL or SVG) without setting up a dedicated QR library — especially inside an agent workflow that already uses x402 micropayments. It is ideal for single-call generation where you need both base64 and a data URL in one response, and when format (PNG vs SVG) and error correction level matter.
Side effects
- text parameter missing or empty — required field not provided
- text exceeds 2000 characters — payload too large for QR encoding
- size outside 64–1024 range — validation error returned
- invalid format or level enum value — rejected with bad request
- network timeout on the Lambda backend — transient 5xx error
- payment not received (402) — x402 micropayment required before response is served
