okx-x402-payment

DEPRECATED legacy alias — x402 + MPP support has been merged into `okx-agent-payments-protocol` (see `references/exact.md`, `references/aggr_deferred.md`, `references/charge.md`, `references/session.md`). This stub exists only so that legacy invocations referencing the old name resolve to a meaningful redirect. If you land here, immediately load `okx-agent-payments-protocol` via the Skill tool and follow it instead. Do NOT execute any payment logic from this stub. All HTTP 402 / x402 / MPP / channel / voucher / session triggers now route directly to `okx-agent-payments-protocol` (Path A in its SKILL.md).
