Autonomous Agent Payments (x402)

•

•

Enables AI agents to autonomously execute payments for APIs and services using the x402 protocol and secure spending controls.

This skill provides a robust framework for AI agents to handle financial transactions without human intervention. By implementing the x402 HTTP payment protocol and non-custodial smart wallets, it allows agents to pay for external services, settle with other agents, and manage budgets through Model Context Protocol (MCP) tools. It is particularly useful for building self-sufficient AI ecosystems where agents must manage their own resource costs while strictly adhering to pre-defined spending policies, allowlisted recipients, and security constraints set by the orchestrator.
