AI agents call get_24h_volume to retrieve information from EDUCHAIN Agent Kit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves aggregated historical data (24-hour trading volume) from a DEX. It has no side effects, does not execute trades, does not modify data, and does not commit financial transactions. It is purely informational and falls squarely into the Read category with low severity risk.
From the tool's definition Tool name 'get_24h_volume' and description 'Get the 24-hour trading volume on SailFish DEX' indicate a read-only query operation that retrieves historical trading data without modifying state or triggering transactions.

{
"version": "1",
"default": "deny",
"tools": {
"get_24h_volume": {}
}
