Agent Payment Execution (x402)
Enables AI agents to execute policy-gated micropayments and settle API fees autonomously using non-custodial wallets and the x402 protocol.
Agent Payment Execution (x402) equips autonomous AI agents with non-custodial ERC-4337 smart accounts and Model Context Protocol (MCP) tooling to pay for APIs, compute, and inter-agent services. By extending the HTTP 402 Payment Required standard, it allows agents to negotiate fees, verify pre-allocated budgets, and execute onchain transactions across Base and X Layer networks. Orchestrators maintain strict control through configurable per-task budgets, session spending caps, address allowlisting, and fail-closed safety checks, eliminating custodial risk while enabling machine-to-machine commerce.
