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. ## OpenAPI ````yaml /openapi.yaml get /live_data/weather/{city} openapi: 3.0.0 info: title: Kalshi Trade API Manual Endpoints version: 3.28.0 description: >- Manually defined OpenAPI spec for endpoints being migrated to spec-first approach servers: - url: https://external-api.kalshi.com/trade-api/v2 description: Production Trade API server - url: https://api.elections.kalshi.com/trade-api/v2 description: Production shared API server, also supported - url: https://external-api.demo.kalshi.co/trade-api/v2 description: Demo Trade API server - url: https://demo-api.kalshi.co/trade-api/v2 description: Demo shared API server, also supported security: [] tags: - name: api-keys description: API key management endpoints - name: orders description: Order management endpoints - name: order-groups description: Order group management endpoints - name: portfolio description: Portfolio and balance information endpoints - name: communications description: Request-for-quote (RFQ) endpoints - name: multivariate description: Multivariate event collection endpoints - name: exchange description: Exchange status and information endpoints - name: live-data description: Live data endpoints - name: markets description: Market data endpoints - name: milestone description: Milestone endpoints - name: search description: Search and filtering endpoints - name: incentive-programs description: Incentive program endpoints - name: fcm description: FCM member specific endpoints - name: events description: Event endpoints - name: structured-targets description: Structured targets endpoints paths: /live_data/weather/{city}: get: tags: - live-data summary: Get Weather Index description: >- Get the Kalshi-computed city temperature index: the canonical minute-resolution series behind hourly temperature markets.
