Single agent-facing endpoint for a payment link. Browsers receive an HTML landing that bounces to the canonical public resource. Agents receive an x402 v2 402 Payment Required challenge on first hit and retry the same URL with a PAYMENT-SIGNATURE header carrying a signed payload for the chosen chain. Successful retries return the settlement receipt; retries against an already settled link return 409; retries before settlement is wired return 501 so callers know to try again later.
