Technical details
Endpoint
GEThttps://x402-qr-api.vercel.app/api/convert?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.002 USDC) programmatic QR code generation via a simple GET request with no authentication beyond x402 micropayment. Ideal for agents operating in x402-enabled environments that need to generate one-off QR codes without managing API keys or OAuth flows.
Side effects
- Missing or empty input parameter returns an error or blank response
- Malformed URL input may produce an unreadable QR code
- Payment failure via x402 (402 status) if USDC balance is insufficient
- Network timeout if Vercel cold-start latency is high
- Input string too long to encode in a QR code returns an error
