How this service works
QR code generator: PNG data URI and SVG for any text or URL. Input: the text or URL to encode.
Output
Returns a JSON object containing: an SVG string of the QR code, a PNG as a base64-encoded data URI, the encoded data string, the QR version number, and the error correction level (e.g. 'M').
Example use cases
QR code for a product landing page
“Make a QR code for https://mystore.example.com/new-arrivals so I can print it on our flyer — I need the SVG version.”
Encoding plain text for a conference badge
“Generate a QR code that encodes the text 'Booth 42, Hall B, TechExpo 2025' so attendees can scan it for directions.”
Shareable link QR for a marketing campaign
“I need a scannable QR code image for this campaign URL: https://promo.example.com/summer-sale — give me the PNG data URI so I can embed it on a webpage.”
Technical details
Endpoint
POSThttps://minty-sprout.onrender.com/v1/qr-code?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both SVG and PNG formats of a QR code in a single call, especially for web embedding (data URI) or print (SVG). It is a simple, low-cost ($0.001 USDC) pay-per-call option with no API key required, ideal for agents that need on-demand QR generation without managing credentials or subscriptions.
Side effects
- Input text exceeds 1500 characters — QR code cannot encode oversized data
- Malformed or empty input returns an error field in the response
- Service unavailable due to cold-start on Render free tier, causing slow or failed responses
- Payment failure (402) if the x402 micropayment is not completed before the request
