# List season types per sport



## OpenAPI

````yaml get /api/v1/season_types
openapi: 3.1.0
info:
  title: TheRundown Sports API
  version: 2.0.0
  description: >
    Real-time and historical sports betting data, odds, lines, and statistics
    across major North American and international sports leagues.


    ## Authentication

    All endpoints (except `/sports` and `/affiliates`) require authentication.
    Pass your API key using one of:

    - **Query parameter**: `?key=YOUR_API_KEY`

    - **Header**: `X-Therundown-Key: YOUR_API_KEY`

    ## Off-the-Board Sentinel Value

    The value **0.0001** indicates a line is "off the board" — the sportsbook
    has temporarily removed pricing (e.g., pending injury news). This is NOT an
    error. Display as "Off Board" or "N/A" in your UI.


    ## Rate Limiting

    Requests are rate-limited per API key tier. Check response headers for
    current limits.


    ## Data Updates

    - Live odds update in real-time during games

    - Use delta endpoints for efficient polling of changes

    - WebSocket connections available for streaming updates


    ## V1 vs V2

    V2 endpoints use market-based data structures (market_id, participants, line
    prices). V1 endpoints use legacy line-based structures (moneyline, spread,
    total objects). V2 is recommended for new integrations.
