Kalshi city temperature 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. Cities: miami, dfw, houston, phl-delaware-valley, puget-sound, sf-bay, greater-boston, southeast-michigan, kansas-city, minneapolis-st-paul, nyc, chicago, la-coastal. Free keyless Kalshi live_data.
