Get open perpetual positions for a Hyperliquid wallet (size, entry, mark, uPnL, ROE, leverage, liquidation price) plus account value, margin used, withdrawable.
AI agents call get_positions 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 purely retrieves and queries public on-chain wallet position data for analytical purposes. It performs no state changes, executes no code, and has no financial transaction capability—it only reads existing blockchain data. The blast radius of misuse is minimal, confined to information disclosure about publicly visible wallet positions.
From the tool's definition Tool description states it 'Get[s] open perpetual positions' and retrieves read-only metrics (size, entry, mark, uPnL, ROE, leverage, liquidation price, account value, margin used, withdrawable).
