List Markets

Polymarket API: GET /markets. To get the NEWEST CREATED markets, use: order='createdAt' with ascending=false and limit. To get markets that START on or after a specific date, use: start_date_min (ISO 8601 format, e.g., '2026-03-10'). IMPORTANT: - start_date_min filters by market.startDate (when the market starts), NOT by market.createdAt (when it was created) - To find newly CREATED markets, use order='createdAt' with ascending=false, NOT start_date_min - start_date_min and order can be used together to find newest markets that start on/after a date.
