Get funding rate history.
AI agents call fundingRate to retrieve information from Aster Finance MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

It is a read-only query operation that does not create, modify, delete, or execute any orders or financial transactions. While the server overall provides access to trading functionality (evident from sibling tools like cancelOrder, cancelAllOpenOrders), this specific tool only fetches market information.
