by 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.

The endpoint answers an unpaid request with an HTTP 402 and a payment challenge. @x402/fetch signs it, pays in USDC, and retries — you get the result back in one call.

FOMC meeting dates and major US economic release dates (CPI, non-farm payrolls, GDP, PCE, retail sales) in one call, each with a days-until countdown, between 'from' and 'to' -- the market-wide catalysts that move every ticker at once. FOMC dates from the Fed's official calendar; release dates live from FRED, and a temporarily-unavailable release is reported explicitly, not silently dropped. Not ticker-specific. $0.01/call.
