Get market movers in one curated endpoint.
AI agents call get_market_movers to retrieve information from Sahmk without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and presents market movement data (likely stocks with largest gains/losses). No side effects, no data modification, no code execution, no financial transactions—purely informational. Low severity because misuse would only expose publicly available market information already visible to any market participant.
