}List Markets
List current prediction markets with pricing data.
Use ?query= to search by keyword in the title (e.g. ?query=bitcoin). Use ?category= to filter by category (e.g. ?category=Crypto) — more reliable than keyword search, which misses markets whose titles say BTC or ETH. Use ?source= to filter by platform.
