Get recent fills (trades) for a Hyperliquid wallet. Returns up to 500 fills from the last N days (default 7).
AI agents call get_fills to retrieve information from Polskidegen Hl Tracker without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical transaction data for a specified wallet without modifying any state or executing external operations. It is purely informational—analogous to querying a blockchain explorer. The blast radius of misuse is minimal; an AI agent cannot cause financial harm or system damage by querying this read-only endpoint, even if queried repeatedly or for unintended wallets.
From the tool's definition Tool description explicitly states 'Get recent fills (trades)' and returns historical trade data. Server description emphasizes 'read-only on-chain wallet analytics.' No modification, deletion, or execution capabilities are described.
