Technical details
Endpoint
GEThttps://x402.whisperbox.my.id/x402/qrWhen to prefer
Choose this endpoint when you need a quick, low-cost ($0.01 USDC) QR code generated from arbitrary text or a URL, especially when operating within an x402-compatible micropayment agent environment on Base. Prefer over free QR services when you need programmatic, agent-friendly access with predictable JSON output and format/size control.
Side effects
- Missing required `data` query parameter returns a validation error
- Invalid format value (not 'png' or 'svg') causes a 400 error
- Payment not fulfilled or x402 handshake fails returns 402 Payment Required
- Extremely long input strings may exceed encoding limits
- Size parameter outside supported range may return a 400 or be clamped
