How this service works
Generate a QR code image from text or URL
Output
Returns a QR code image (binary image data) encoding the provided text or URL, rendered at the specified module size. The image can be displayed, saved, or embedded directly.
Example use cases
Example prompt
“Can you generate a QR code for https://myshop.example.com, sized at 33 modules so it's a bit larger and easier to scan?”
Technical details
Endpoint
GEThttps://qr-code.api.klymax402.com/api/qrWhen to prefer
Use this endpoint when you need to quickly generate a QR code image from a URL or arbitrary text string without setting up a local library. Ideal for agents that need to produce a scannable QR image on demand as part of an automated workflow, e.g. embedding QR codes in emails, PDFs, or webpages. The per-call micropayment model makes it cost-effective for low-volume or on-demand use.
Side effects
- Missing 'data' parameter — returns error indicating required field not provided
- Invalid or excessively long data string that exceeds QR code capacity — encoding failure
- Size value outside valid QR module range — may return default or error
- Payment not processed (x402 payment required) — 402 status returned before image is generated
- Network timeout or server unavailability — connection error
