Use this endpoint when you need to analyze trading volume split by YES/NO outcomes for a specific Polymarket prediction market. It is ideal for agents building market analytics dashboards, comparing buyer sentiment via volume, or monitoring how conviction is distributed across outcomes for a given market hash. Prefer this over generic market data APIs when you specifically need outcome-level volume breakdown on Polymarket.
