Kalshi city temperature index
POST https://agent402.tools/api/kalshi-weather-index
Kalshi's own minute-resolution city temperature index (Fahrenheit), the series its hourly temperature markets settle on, computed from weighted member stations. Ask for a trailing window (lastSec, default one hour, max 7 days) or a from/to window; detailed adds every station's reading per minute; includeCalibrations adds the published station-weight and offset timeline.
