Prediction Market Series Browser

Every open market under one exact Kalshi series ticker (e.g. Fed rate decisions, recession odds) -- the reliable, exhaustive complement to /prediction-markets' best-effort keyword scan. Unlike keyword search, series_ticker is a genuine exact server-side filter. An empty result can mean an unknown series_ticker OR a real series with nothing open right now -- Kalshi's API returns the same response for both, flagged via the 'note' field. Supports optional limit (default 25, max 50). $0.01/call.
