Use this first when the user asks what Polymarket thinks about a topic, how likely something is, or names a market without a link. Searches every Polymarket market by keyword (Polymarket's own full-text search) or by a polymarket.com link and returns events with all their outcomes, current prices, 24h volume and end dates, plus the slug to pass to the other tools. Use status='resolved' for past markets and how they settled.
