AI agents call get_financial_indicators to retrieve information from Sfc Data without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Classification as Read is appropriate; severity is low because misuse would only result in accessing market data that is typically public or authorized for users of the API.
