# 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: >
    **Resolve the event first.** Ambiguous date, team, player, or timezone? The
    agent asks instead of guessing.


    **Every price carries evidence.** Event, market, affiliate ID, line, and the
    price update time. A fetch time is not freshness.


    **Missing stays missing.** No remembered odds, no synthetic prices, no
    filled gaps.


    **IDs come from the API.** Sports, markets, and affiliates are discovered at
    runtime. Retired affiliates stay out.


    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.
    Send your API key from a private server-side environment variable in the
    `X-TheRundown-Key` header.

    The query-key security scheme is retained for compatibility with existing
    integrations and deprecated for new integrations; do not put keys in URLs,
    prompts, browser bundles, or public code.

    ## 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.
