# Agent Payment Execution (x402) Enable AI agents to make policy-gated payments with built-in spending controls. Uses the x402 HTTP payment protocol and MCP tools so agents can pay for external services, APIs, or other agents without custodial risk. ## When to Use Use when: your agent needs to pay for an API call, purchase a service, settle with another agent, enforce per-task spending limits, or manage a non-custodial wallet. Pairs naturally with cost-aware-llm-pipeline and security-review skills. ## Decision Tree Choose the integration path based on whether your agent is buying access to a paid API or charging others for one: | Need | Recommended path | |------|------------------| | Agent pays a 402-gated API on Base or another agentwallet-supported chain | Use `agentwallet-sdk` as an MCP payment server with strict spending policy | | Agent pays a 402-gated API on X Layer | Use OKX Agent Payments Protocol from `okx/onchainos-skills`; `okx-x402-payment` is a deprecated legacy alias | | TypeScript API charges agents | Use OKX Payments TypeScript seller SDK docs for Express, Hono, Fastify, or Next.js | | Go API charges agents | Use OKX Payments Go seller SDK docs for Gin, Echo, or `net/http` | | Rust API charges agents | Use OKX Payments Rust seller SDK docs for Axum | | Java API charges agents | Use OKX Payments Java seller SDK docs for Spring Boot 2/3, Java EE, or Jakarta | | Python API charges agents | Check the current OKX Payments repository before implementation; a
