Endpoint
GEThttps://x402-qr-api.vercel.app/api/qrcode?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-use QR code generation via the x402 micropayment protocol at $0.01 USDC per call — ideal for agents operating in Web3 or x402-enabled environments where standard free-tier generators are unavailable or unsuitable.
Side effects
- Missing or empty input parameter returns an error or blank image
- Malformed URL passed as input may produce an unscanneable QR code
- Payment not fulfilled via x402 protocol results in a 402 Payment Required response
- Service downtime on Vercel deployment returns 500 or 503
- Overly long input string may exceed QR code data capacity and fail encoding
