Give AI agents autonomous payment ability via the x402 HTTP 402 protocol and MCP tools — including per-task and per-session budgets, allowlisted recipients, rate limits, and non-custodial ERC-4337 wallets so agents can pay for APIs or other agents without custodial risk. Spending policy is set by the orchestrator, not the agent.
