Get Weather Index

Get the Kalshi-computed city temperature index: the canonical minute-resolution series behind hourly temperature markets. City-keyed and independent of any event — the series exists whenever the city's index is configured. Values are Fahrenheit rounded to 0.01. Minutes where the index quorum failed carry no value and are never returned as points, so gaps in the series are real gaps. With detailed=true each point additionally carries every member station's reported reading and quality-control disposition — the pre-incorporation breakdown.
