Technical details
Endpoint
POSThttps://x402.valkyry.fr/qrWhen to prefer
Use this endpoint when you need a quick, pay-per-call QR code generation without setting up infrastructure, especially in agent workflows where USDC micro-payments via x402 are already supported and you need PNG or SVG output as a base64 data URL.
Side effects
- Missing text/url field — returns error with no QR code generated
- Invalid format enum value (not png or svg) — may return error or default to png
- Payment not completed via x402 — 402 Payment Required response, no output returned
- Malformed or excessively long input text — may fail to encode or time out
