Daily snapshots for a specific market: token price, TVL, volume, revenue, rates history, and active user counts.
AI agents call get_market_snapshots to retrieve information from Graph Lending without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves historical market data across lending protocols. It performs no writes, deletions, code execution, or financial transactions. The data retrieval is read-only with no side effects. The low severity reflects minimal blast radius—querying historical market snapshots cannot cause harm even if misused by an AI agent.
