Agent Payment Execution (x402) provides a robust framework for AI agents to manage their own financial transactions through the x402 HTTP payment protocol and Model Context Protocol (MCP) tools. By integrating non-custodial ERC-4337 smart accounts and strict spending policies, developers can empower agents to independently purchase API access, settle with other agents, or acquire digital services without custodial risk. This skill is essential for building autonomous AI ecosystems where financial settlement is a core part of the agentic workflow, offering a secure way to manage per-task budgets and transaction auditing.
