Overview

This is a coherent paid API helper, but it can lead an agent to make wallet-signed x402 payments without clear confirmation or spending-limit instructions.

Install only if you intend to use x402 pay-per-use API calls. Use a dedicated low-balance wallet, verify the payment requirements and amount before every request, avoid putting a primary private key in code or chat, and pin/review the external payment package before using it with wallet credentials.

Missing User Warnings

Medium

• Confidence: 97% confidence
• Finding: The skill explicitly says payment handling happens automatically when using the provided SDKs/CLI, but it does not give a prominent warning that invoking the examples can cause real paid transactions. In an agent-skill context, this can lead users or autonomous agents to trigger onchain payment authorizations without informed consent, creating financial loss risk even if the per-call charge is small.
