How this service works
320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.
Output
Returns a JSON object containing a base64-encoded QR code image string, the image format (e.g. PNG), and the rendered pixel size. The agent can decode the base64 string to display or embed the QR code image directly.
Example use cases
QR code for restaurant menu link
“Make me a QR code for 'https://bistrodupont.com/menu' at 256 pixels — I want to print it on table cards.”
QR code for crypto payment address
“Generate a QR code encoding my Ethereum address '0xABCD1234...EFGH' so customers can scan to pay me.”
QR code for WiFi credentials
“Create a QR code from the text 'WIFI:S:MyHomeNetwork;T:WPA;P:supersecret123;;' at 400 pixels so guests can connect without typing the password.”
Technical details
Endpoint
POSThttps://whatchuneed.vercel.app/api/util/qrWhen to prefer
Choose this endpoint when you need a quick, pay-per-call QR code generation with no API key setup, especially within an agent pipeline already using the whatchuneed x402 ecosystem. Ideal for one-off or low-volume QR code generation tasks where simplicity and breadth of the whatchuneed platform matter more than specialized QR code SaaS features.
Side effects
- Missing required 'text' field returns a validation error
- Extremely long text strings may exceed QR code data capacity and fail encoding
- Invalid size values (non-integer or negative) may return an error or be ignored
- Network or upstream service unavailability may result in a 5xx error
- Payment failure via x402 protocol prevents the call from being processed
