WHAT IT DOES

What currency_api_list does on UnClick

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

RISK

Why currency_api_list is rated Low

This tool simply enumerates currency codes from an external API. It retrieves information without modifying, executing external operations, deleting data, or creating financial obligations. The blast radius of misuse is minimal—an agent cannot cause harm by listing currency codes.

From the tool's definition Tool description states 'List all supported currency codes' — a pure retrieval operation with no side effects. The verb 'list' and the action of querying a static reference dataset confirm this is a read-only query.
