Three payment paths, distinguished by HTTP signature: accepts-based 402 (challenge in body for v1 or PAYMENT-REQUIRED header for v2), WWW-Authenticate: Payment 402 (channel-capable, intent="charge" or "session"), and a2a-pay (paymentId-based, no 402). Shared steps below (detect → decode → confirm → wallet check), then dispatch to a reference.
Okx Agent Payments Protocol is a community-contributed Claude Code skill in the ai-tooling sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/okx-agent-payments-protocol/ and loads when your prompt matches the skill's trigger.
When to invoke it: 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. Covers x402 (exact, exact+Permit2, upto, aggr_deferred), MPP (charge / session), and a2a-pay paymentId flows.
