## When to prefer this

Choose this endpoint when you need a quick, pay-per-call QR code generation with no API key setup, especially in agent workflows that already use x402/USDC micropayments on Base. It is well-suited for one-off or low-volume QR generation tasks embedded in automated pipelines.

## Known failure modes

- Empty or missing query string returns an error or blank response
- Extremely long input strings may exceed encoding limits
- Invalid or malformed input may produce an unreadable QR code
- Service downtime on the Vercel deployment may return 5xx errors
- Payment failure via x402 protocol causes the request to be rejected before processing
