Security checks for vulnerabilities and agentic risk

Overview

This skill is a paid data lookup, but it asks an agent to use a full EVM private key for automatic wallet payments without clear spending controls.

Review before installing. Use only a dedicated low-balance Base wallet for this skill, expect each invocation to spend USDC, and avoid letting an agent call it automatically or repeatedly unless you have external spending limits and monitoring in place.

Finding

The skill explicitly states that the x402 client 'handles payment authorisation automatically' and requires an EVM private key, but it does not present a clear, prominent warning that invoking the example/request will spend funds from the user's wallet. In an agent setting, this can cause unintentional paid transactions and repeated charges if the skill is called automatically or in loops, especially because the API is framed as frictionless and subscription-free.
