How are spending limits enforced?

Spending limits are enforced via a SpendingPolicy at the orchestrator level before delegation, preventing agents from independently increasing their own budget or paying unauthorized recipients.

What is the x402 protocol?

x402 is an extension of the HTTP 402 (Payment Required) status code that enables machine-to-machine negotiation and automated payment processing without human intervention.

Is my wallet safe with this skill?

Yes, it uses non-custodial ERC-4337 smart accounts, meaning the agent holds its own keys and follows pre-defined spending policies set by the orchestrator, minimizing custodial risk.

Does this work with other AI frameworks?

While optimized for Claude Code, it uses the standard Model Context Protocol (MCP), making it compatible with any agent framework that supports MCP tools.

Can I use this on mainnet?

Yes, it is compatible with networks like Base Mainnet, though it is highly recommended to perform initial development and testing on the Base Sepolia testnet.

Agent Payment Execution x402 - Claude Code Skill

Agent Payment Execution (x402) is a specialized skill for Claude Code that integrates the x402 HTTP payment protocol and Model Context Protocol (MCP) tools to give AI agents financial autonomy. It allows agents to pay for API calls, microservices, or peer-to-peer interactions while maintaining high security through ERC-4337 non-custodial smart accounts. By implementing strict spending policies, such as per-task and per-session budget limits and recipient allowlisting, developers can safely delegate financial tasks to AI agents without custodial risk or the threat of runaway spending.
