This pulls a comprehensive profile of any Ethereum wallet using Nansen's API. You get identity labels (Smart Trader, Fund, etc.), current token balances with USD values, 30-day PnL including win rate and top traded tokens, recent transactions, Hyperliquid perp positions if they exist, and frequent counterparties. It's basically the full context you need when researching an unknown address or tracking what a known wallet is up to. The counterparties view is especially useful for spotting who they're trading with most. Requires a Nansen API key and the nansen-cli npm package.
