agent-payment-x402

You can enable autonomous payments for AI agents without custodial risk by enforcing per-task budgets and wallet control using non-custodial ERC-4337-style accounts and the x402 protocol. This approach prevents unauthorized spending through strict policy enforcement.

The x402 protocol is a standard used to enforce per-task and per-session spending limits for AI agents. It integrates with MCP tools to manage non-custodial wallets and ensure payments only go to allowlisted recipients during orchestration.

You can set per-task spending limits by configuring the x402-based workflow and using standard MCP tools like check_spending and send_payment. This ensures your autonomous AI agents operate within strict, predefined budget policies.

Yes, you can use ERC-4337-style accounts to manage non-custodial wallets for AI agents. This allows secure autonomous payments without giving the agent direct custody of the underlying funds, maintaining strict policy enforcement.

The available MCP tools for agent wallet management include get_balance, send_payment, check_spending, and list_transactions. These tools integrate with the x402 workflow to manage autonomous payments and track spending against budget limits.

Allowlisted recipients restrict autonomous agent payments so funds can only be sent to pre-approved addresses. This constraint is enforced by the x402 protocol policy during the agent orchestration workflow to prevent unauthorized transfers.
