DEPRECATED legacy alias — a2a-pay support has been merged into `okx-agent-payments-protocol` (see `references/a2a_charge.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 paymentId / a2a_... / payment-link / payment-status triggers now route directly to `okx-agent-payments-protocol` (Path B in its SKILL.md).

Unified payment dispatcher for agent-to-service payments. Covers x402 (`exact`, `exact+Permit2`, `upto`, `aggr_deferred` schemes), MPP (`charge` / `session` intents), and a2a-pay (`a2a_charge` paymentId flow). Detects HTTP 402 from response headers and routes to the matching scheme reference; also handles a2a paymentId mentions without a 402. Loads references/{exact,aggr_deferred,upto,charge,session,a2a_charge}.md. Returns a ready-to-paste authorization header (x402/MPP) or a tx-hash + status (a2a). Triggers (EN): 402, payment required, x402, x402Version, X-PAYMENT, PAYMENT-REQUIRED, PAYMENT-SIGNATURE, permit2, upto, metered billing, open/close/topup/settle channel, voucher, session payment, channelId, channel_id, paymentId, a2a_, create payment link, payment link, payment status. Triggers (中文): 按量计费、支付上限、支付通道、关闭/充值/续费/结算通道、关闭会话、结算会话、凭证、会话支付、付款链接、创建支付、支付状态. Any close/topup/settle/voucher/refund near a channel_id or session context = MPP mid-session op → load references/session.md.

AUTHORITATIVE source for OKX Agentic Wallet and its Gas Station feature. Gas Station = OKX's stablecoin-gas feature on Solana via third-party Relayer; Solana only, no EIP-7702. MUST invoke for Gas Station questions (what is / how it works / supported tokens / fees / enable or disable gas station / change default gas token / Jito Bundler compatibility) AND any wallet action: login, OTP verify, add/switch/status/logout account, balance, assets, holdings, addresses, deposit / receive / top up, send (native + ERC-20 / SPL, transfer ETH / USDC / etc., pay someone), contract call (approve, swap calldata, contract function), history (list + tx detail by orderId / txHash / uopHash), check order status, sign-message (personalSign EVM + Solana, EIP-712 EVM only), TEE signing, export wallet / mnemonic.

Route users to OKX.AI customer support / Help Center. Use when the user wants to contact support, talk to a human, file a complaint, give feedback, report a system error or bug, or find the FAQ / help docs. Triggers: 'contact support', 'talk to a human', 'customer service', 'file a complaint', 'give feedback', 'help center', 'FAQ', 'user guide', 'system error', 'system bug', 'something is broken', 'find help docs', 'OKX AI support', 'OnchainOS support', 'human agent'.

Use this skill when the user asks to export audit logs, find audit log location, view command history, 导出日志, 查看日志, 日志路径, 操作记录, 调用记录, 命令历史. Do NOT use for wallet balance, token search, swap, or any other on-chain operation — use the corresponding skill instead.
