How this service works
Generate a PNG QR code URL for payment and onboarding payloads (upstream probed live)
Output
Returns a JSON object with an 'ok' boolean, a 'png_url' string pointing to the generated PNG QR code image, and a 'service' identifier string. The agent can use the png_url directly to display, embed, or share the QR code.
Example use cases
QR code for crypto payment link
“Generate a 256-pixel QR code image for this payment URL so my customer can scan it at checkout: 'https://pay.vendsdk.com/pay?to=0xABC&amount=10'”
Onboarding invite QR code
“Create a 512-pixel QR code for my onboarding link 'https://app.myproduct.com/invite?code=XYZ987' so I can print it on a flyer”
Wallet address QR for display
“Make a QR code at 128 pixels that encodes my Bitcoin wallet address 'bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh' so people can scan to send me funds”
Technical details
Endpoint
GEThttps://vendsdk.com/api/v/qr-codeWhen to prefer
Choose this endpoint when you need a fast, hosted PNG QR code URL from an arbitrary string payload — especially for payment links, wallet addresses, or onboarding URLs — without setting up your own QR rendering infrastructure. It is particularly well-suited for agent workflows that already operate in the x402 payment ecosystem and need per-call, pay-as-you-go QR generation at low cost.
Side effects
- Missing or empty 'data' query param returns an error response with ok:false
- Pixel size outside the 128–512 range may be rejected or clamped
- Malformed or excessively long payload strings may cause encoding failure
- Network or upstream rendering errors may result in a non-200 response
