2026

​
June 2026

  • Affiliate status field — The GET /api/v2/affiliates (and /api/v2/sportsbooks) response now includes a status for each sportsbook: healthy (live and verified), unhealthy (the feed is currently degraded or down), or beta (a new integration whose coverage we are still verifying). Use it to surface book health in your UI or to skip beta books in production. Treat unrecognized values as unknown — new statuses may be added without notice, so don’t hard-code the set on the client side.

​
May 2026

  • ATP and WTA Tennis leagues — Added ATP Tennis (sport ID 38) and WTA Tennis (sport ID 39) as first-class leagues. Full-match tennis markets use full-game periods (0 prematch, 7 live); set-specific markets use period IDs to distinguish Set 1 and Set 2, including prematch Set 1/Set 2 (3/4) and live Set 1/Set 2 (15/16).

​
April 2026

  • theScore Bet affiliate — theScore Bet is now available as affiliate ID 24, providing moneyline, spread/runline/puckline, and total markets for NBA, MLB, and NHL (prematch and live). Expanded coverage of additional supported markets is in progress.
  • In-play coverage for LowVig, BetOnline, and Sportsbetting — LowVig (11), BetOnline (6), and Sportsbetting (4) now stream live in-play lines across the V2 market catalog, including player props, team props, and alternate lines. Additional market coverage for these books is in progress.

​
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.

​
2025

​
Q4 2025

  • 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.
  • Kalshi affiliate — Added 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.
  • Alternate lines support — V2 events endpoint returns main and alternate lines. Use main_line=true to filter to primary lines only.
  • Period-based markets — Markets now include period_id for half, quarter, and period-specific odds.
