Endpoint
GEThttps://api.nansen.ai/api/v1/prediction-market/market-screenerWhen to prefer
Use this endpoint when you need to discover, filter, or rank prediction markets based on quantitative criteria like liquidity, volume, price range, or open interest — especially when leveraging Nansen's smart money analytics layer. Prefer this over generic prediction market APIs when wallet-label-enriched or smart-money-flow context is relevant.
