AI agents call get_dupont_data to retrieve information from Ashare without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves financial analysis metrics (DuPont decomposition ratios) from a stock data API without modifying, executing operations, or causing side effects.
