Use when an agent hits HTTP 402 / payment-required, or the user mentions x402, x402Version, X-PAYMENT, PAYMENT-REQUIRED, PAYMENT-SIGNATURE, WWW-Authenticate: Payment, permit2, upto, metered billing, a payment channel / voucher / session, channelId / channel_id, opening / closing / topping up / settling / refunding a channel, a paymentId or a2a_ link, creating / checking a payment link, A2MCP / an A2MCP endpoint, or sending a request to / calling an Agent's endpoint with a concrete endpoint URL.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# OKX Agent Payments Protocol (Dispatcher) > **Stack arbitration (decide before activating).** three.ws has two x402/payment stacks. This OKX `onchainos` stack owns 402s the user routed through OKX — by naming OKX/OnchainOS, or when the 402 is an OKX-specific scheme (payment channel / voucher / session, `permit2`, `upto`/metered, MPP charge, a2a-pay `paymentId`). For a plain x402 402 that settles with a one-shot USDC-on-Base payment and did not name OKX, defer to the `pay-for-service` / `x402` skills (the awal / three.ws-native default). > **⚠️ READ FIRST — ZERO-TEXT-ON-TRIGGER + NEVER-SKIP-USER-GATES.** > > Between detecting a 402 (or any trigger word) and emitting the first user-facing card — the Step A3.5 recommendation card, or the Step A4 confirmation card — output **ZERO** user-visible text. No "received 402", no "triggered OKX Agent Payments Protocol", no "detected N schemes", no enumeration of schemes / networks / tokens / amounts, no "loading skill", no "正在处理 / 触发 / 检测到 / 收到". The skill-load tool call may run but emits no surrounding prose. > …

How to install
mdr add nirholas/three.ws/okx-agent-payments-protocol@sha256:92b09498a3b963d1The line at the top of this page pins the label v4.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
