x402 Agent Payment Execution
Equips AI agents with autonomous payment capabilities using the x402 protocol, non-custodial smart accounts, and strict budget controls.
The agent-payment-x402 skill integrates automated payments into AI agent workflows through the Model Context Protocol (MCP) and the HTTP 402 payment standard. It enables agents to autonomously negotiate pricing, pay for third-party APIs, and settle microtransactions with other agents using ERC-4337 non-custodial smart accounts. Designed for security and reliability, it allows orchestrators to enforce fail-closed spending policies—including per-task budgets, per-session spending caps, rate limiting, and recipient allowlists—preventing unauthorized charges and ensuring full auditability.
