Cross-venue prediction-market keyword search across...
Cross-venue prediction-market keyword search across Polymarket, Kalshi, and Limitless Exchange in one call. Pass q (required); filter by status (open/closed) and cap per-venue with limit. Each hit is tagged with its venue and returns the question, live YES/NO price (0-1 implied probability), USD volume, close date, and the venue URL — for finding the same real-world question wherever it trades. Read-only, keyless.
