Pull trade history and P&L breakdowns for any Polymarket wallet address using Nansen's API. You get timestamped trades with market context, USDC values, and profit/loss across resolved and unresolved positions. The workflow is specific: find active trader addresses from market trade logs first, not holder lists, since holders might have empty trade history. Useful when you're trying to understand what a specific wallet is betting on, whether they're actually profitable, or if their large positions in certain categories signal real conviction versus luck. Requires a Nansen API key and the nansen-cli Node package.
