How this service works
Generate a PNG QR code URL for payment and onboarding payloads (upstream probed live)
Output
Returns a JSON object containing a PNG image URL (png_url) pointing to the generated QR code, a boolean ok status, and a service identifier string. The PNG can be directly embedded or shared.
Example use cases
QR code for crypto wallet
“Can you create a QR code PNG for my Bitcoin wallet address 'bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh' at 300 pixels so customers can scan it to send payments directly?”
Onboarding flow QR link
“I need a scannable QR code image for the URL 'https://app.myproduct.com/onboard?ref=welcome2024' at 256 pixels so I can drop it into my welcome email for new users to scan and get started quickly.”
Checkout page QR embed
“Can you generate a 512-pixel PNG QR code for the string 'https://shop.example.com/cart/checkout?session=XYZ987' that I can embed directly on my checkout confirmation page for mobile users to scan?”
Technical details
Endpoint
GEThttps://vending-machine-seven.vercel.app/api/v/qr-codeWhen to prefer
Use this endpoint when you need a quick, hosted PNG QR code URL from an arbitrary string or payload — especially for payment links, crypto addresses, or onboarding flows — and want a per-call micro-payment model rather than a subscription API key. Ideal for agents that need an embeddable image URL rather than raw QR binary data.
Side effects
- Missing required 'data' query parameter returns an error
- Size value outside 128–512 range may be rejected or clamped
- Upstream QR rendering service unavailable causes a 5xx error
- Payment not provided or x402 authorization missing returns 402 Payment Required
- Extremely long data strings may exceed QR code capacity limits
