A series represents a template for recurring events that follow the same format and rules (e.g., "Monthly Jobs Report", "Weekly Initial Jobless Claims", "Daily Weather in NYC"). Series define the structure, settlement sources, and metadata that will be applied to each recurring event instance within that series. ## OpenAPI ````yaml /openapi.yaml get /series/{series_ticker} openapi: 3.0.0 info: title: Kalshi Trade API Manual Endpoints version: 3.34.0 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: /series/{series_ticker}: get: tags: - market summary: Get Series description: ' Endpoint for getting data about a specific series by its ticker.
