Get compressed, aggregate market trades.
AI agents call aggTrades 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.
This tool retrieves market trade data for analysis purposes only. It does not create orders, execute trades, delete data, or commit financial transactions. While it is part of a cryptocurrency trading platform, accessing market data itself carries minimal risk—the risk lies in how that data is used by downstream tools like cancelOrder or position management functions.
