## Why three_price is rated Low

This tool retrieves pricing data from external sources (Jupiter and Birdeye) without modifying, executing, or consuming resources. It is a straightforward data retrieval endpoint with no capability to alter state, execute code, or incur financial obligations.

From the tool's own definition: "The description explicitly states 'Read-only — no signer or payment required' and the tool returns 'the live USD price of $THREE', which is a pure query operation with no side effects."

## Use case

AI agents call three_price to retrieve information from $THREE Token without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

    "three_price": {}
  }
}
