How this service works
Generate a QR code from any text or URL. Returns base64-encoded PNG.
Output
Returns a JSON object containing the QR code image as a base64-encoded PNG data URI (e.g. data:image/png;base64,...), the size in pixels, and the format ('png'). The image can be directly embedded in HTML img tags or saved to disk.
Example use cases
Dynamic invoice payment QR codes

Event ticket distribution workflow
“Turn this event link into a scannable QR code PNG and embed it in the confirmation emails we're sending to registrants.”
Contact card sharing for agents
“Create a QR code that encodes my business contact info so I can include it in automated signatures when my AI responds to partnership inquiries.”
