Check your wallet
AI agents call wallet_usage to retrieve information from APIMesh MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves wallet information for the user's account (read operation). While the server supports financial transactions via Stripe and x402 payments, this specific tool only reads wallet state without executing payments or modifying financial data. The blast radius is minimal—an AI agent querying wallet status poses no financial or operational risk.
From the tool's definition Tool name 'wallet_usage' and description 'Check your wallet' indicate querying/retrieving account balance or usage metrics. No modification, deletion, or financial transaction occurs.
