AI agents call storm_get_market to retrieve information from Storm without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves market data from a prediction-market API without any side effects. It queries information about a market on a venue but does not create, modify, delete, or execute anything. This is a straightforward Read operation with minimal security risk.
From the tool's definition Tool description states 'Fetch the canonical Storm view of a single market' — fetch is a read operation that retrieves data with no modification.
