2026

​
March 2026

  • Live market variants now default — V2 event endpoints now return live moneyline, spread, and total (IDs 41, 42, 43) alongside the standard prematch markets by default. Integrations that pass explicit market_ids are unaffected.
  • Faster live score updates — Live score data now reflects in-game changes much faster. The score object on event responses — including event_status, display_clock, game_period, and current scores — updates more frequently during live games.
  • Ultra tier latency improvements — Ultra tier subscribers now receive WebSocket price updates in real time with no batching delay. REST endpoints for Ultra tier also return fresher data.

​
February 2026

  • exclude_status parameter — New query parameter for V1 and V2 event endpoints. Pass exclude_status=STATUS_POSTPONED,STATUS_CANCELED (comma-separated) to filter out postponed and canceled games before they reach your application.
  • delta_last_id bootstrap — V2 markets responses now include meta.delta_last_id, a starting cursor for delta polling. Use it to initialize /api/v2/markets/delta immediately after a snapshot without missing updates.
  • Subscription plan headers — V2 responses now include headers that surface your subscription tier, rate limits, allowed bookmaker IDs, and active feature flags. Useful for building adaptive clients and debugging plan entitlements.
  • Retry-After headers on rate limit responses — All 429 Too Many Requests responses now include a Retry-After header indicating when you may retry.
  • MLB Spring Training migration — MLB Spring Training events have been migrated from sport ID 3 to a dedicated sport ID 30, isolating preseason games from the regular season. This follows the same pattern used for NBA Summer League (32) and other season-specific sport IDs. If you consume spring training data, update your integration to query sport ID 30.
  • OpenAPI spec published — Full OpenAPI 3.1 specification now available for automated client generation and tooling integration.
  • Market 553 deprecated — use market 410 — The any_time_goal_scorer market (ID 553) has been consolidated into the to_score market (ID 410). Market ID 553 will no longer return data. Update integrations that query market 553 to use market 410 instead.

​
January 2026

  • V2 Markets WebSocket — New wss://therundown.io/api/v2/ws/markets endpoint for real-time market and price updates, replacing the legacy V1 WebSocket. Supports granular filtering by sport, market, event, and affiliate.
  • price_delta field — Pass include=price_delta on V2 event endpoints to receive the previous price and direction of change alongside current odds. Useful for animating line movement on page load.
  • live_variant_id field — Market objects now include a live_variant_id mapping prematch markets to their live equivalents, enabling seamless prematch-to-live market switching.

  • Player prop markets expansion — Added combo prop markets: PRA (93), Points + Assists (99), Points + Rebounds (297), Rebounds + Assists (298). Added live player prop markets for points (90), assists (91), three-pointers (92), rebounds (982), blocks (983), and turnovers (984).
  • Market line price history — New GET /api/v2/events/{eventID}/markets/history and GET /api/v2/events/{eventID}/markets/{marketID}/history endpoints for full price history with RFC 3339 time range filtering. Opening and closing line endpoints added at /openers and /closing.

​
Q3 2025

  • V2 markets delta endpoint — GET /api/v2/markets/delta returns only markets that have changed, providing a more efficient alternative to full event polling.
  • Team totals market — Market ID 94 added for individual team over/under totals.
  • ESPN Bet and Kalshi affiliates — Added ESPN Bet (affiliate ID 24) and Kalshi (affiliate ID 25) to tracked sportsbooks.

​
Q2 2025

  • V2 API general availability — The V2 market-based data model is now the recommended API version. V1 remains available but new features are V2-only.

  • Period-based markets — Markets now include period_id for half, quarter, and period-specific odds.
