## When to prefer this

Use this endpoint when you specifically need smart money or whale positioning signals on a Polymarket market — not just price or volume data. Prefer this over general market endpoints when you want to understand how sophisticated, informed, or high-capital traders are positioned relative to the market consensus, especially for trading strategy, research, or market sentiment analysis.
