How this service works
Generate a QR code (PNG base64) from text/URL/WiFi/vCard with size and error-correction control.
Output
A base64-encoded PNG image of the generated QR code, ready to embed in HTML (data URI), save to disk, or pass to another service. The image dimensions and error-correction level match the requested parameters.
Example use cases
Restaurant menu QR code for tables
“Create a QR code for https://bistromaison.com/menu at 300 pixels with high error correction — I need to print it on table cards.”
WiFi network QR code for guests
“Make a QR code that lets guests connect to my WiFi — the network is GuestNet, password is Sunny2024, it's WPA2 type, and I want a large 500px version.”
vCard contact QR code for business cards
“Generate a QR code from my vCard — name is Sarah Lim, phone +1-415-555-0192, email sarah@lim.design — medium size, medium error correction, so I can embed it on my business card.”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/qr-generateWhen to prefer
Choose this endpoint when you need a server-side, programmatically generated QR code returned as a base64 PNG — especially when you need precise size control, specific error-correction levels, or support for structured QR formats like WiFi or vCard. Ideal for agents automating print assets, contact sharing, or network access flows within the x402 micropayment ecosystem.
Side effects
- Invalid or empty input text returns a 400 error
- Unsupported QR data type (e.g. malformed vCard) may cause generation failure
- Extremely large size values may be rejected or capped
- Missing required fields returns a validation error
- Payment failure (x402) if USDC balance is insufficient
