agent-payment-x402

Enable autonomous payments by using non-custodial wallets where AI agents hold their own private keys, enforced by strict per-task spending policies. This approach avoids custodial risk while allowing agents to pay for external APIs, services, or other agents automatically.

The x402 protocol integration automates payment negotiation and retries on 402 Payment Required HTTP responses. It allows AI agents to automatically handle payment flows when accessing paid external services or APIs without manual intervention.

Configure per-task and per-session budgets, allowlisted recipients, and rate limits to prevent overspending. You need to initialize a per-task budget policy and configure spending limits before executing paid agent actions.

Yes, MCP integration exposes standard tools to slot into existing Claude Code agent harness setups. You configure the MCP client with a pinned dependency version and initialize your per-task spending policy within that orchestration environment.

Security guidance includes pinning dependencies, auditing tool usage, and maintaining strong safeguards around private keys. Non-custodial wallet controls ensure agents hold their own keys with policy-enforced spending limits to prevent unauthorized transactions.

Configure the MCP client with a pinned dependency version, initialize a per-task budget policy, and run a small paid action in a test environment. This validates the spending controls and x402 payment protocol integration before production deployment.
