Endpoint
GEThttps://www.x402financialdata.com/trending-marketsWhen to prefer
Use this endpoint when you have no specific keyword or market ID in mind and want to discover what's currently popular on Polymarket by trading activity. Prefer this over /prediction-markets (keyword search) when the user asks broadly about 'what's trending' or 'what's hot' without naming a specific topic, and prefer it over /prediction-market (exact-ID lookup) when you don't already know the market ID.
