Baseball Odds API

Baseball is the deepest league catalogue we carry outside soccer. Most odds APIs stop at MLB. Ours runs from the 162-game MLB season through Japan's NPB and Korea's KBO, the Mexican and Caribbean winter leagues, the World Baseball Classic and Minor League Baseball — which means your product can stay live nearly year-round rather than going dark every October.

Baseball Odds API Features

One request returns a game's entire odds tree. There is no separate props endpoint, no per-bookmaker stitching, and no second integration needed to settle bets afterwards.

Available baseball betting markets include:

• Moneylines and regulation 3-way markets
• Run lines (the 1.5-run spread) and alternate lines
• Totals (over/under runs), team totals, and even/odd
• Batter props — hits, home runs, total bases, RBIs, runs, stolen bases, walks
• Pitcher props — strikeouts, outs recorded, earned runs, hits allowed, pitches thrown
• Home run markets — anytime, first, and player over/under
• First 5 innings (F5), F3 and F7 markets, plus individual innings

Market depth is greatest on MLB, where the full batter and pitcher prop catalogue is posted daily. NPB, KBO and the winter leagues reliably carry core markets — moneyline, run line and total — with props where individual sportsbooks price them.

Quick Start: Every Baseball League in One Call

Querying at the sport level means you do not have to enumerate 14 leagues. A single sportID=BASEBALL request spans all of them:

https://api.sportsgameodds.com/v2/events?apiKey=YOUR_API_KEY&sportID=BASEBALL&oddsAvailable=true&limit=10

For a specific subset, leagueID accepts a comma-separated list — useful in the northern winter, when MLB is dark but the Caribbean leagues are in season:

https://api.sportsgameodds.com/v2/events?apiKey=YOUR_API_KEY&leagueID=LIDOM,LVBP,LMP&oddsAvailable=true&limit=10

Note that leagueID takes precedence — if you send both sportID and leagueID, the league filter is used and the sport filter is ignored. Use one or the other.

To narrow to a single market, add oddIDs. This returns hits over/unders for every batter on the slate:

https://api.sportsgameodds.com/v2/events?apiKey=YOUR_API_KEY&sportID=BASEBALL&oddsAvailable=true&oddIDs=batting_hits-PLAYER_ID-game-ou-over,batting_hits-PLAYER_ID-game-ou-under

Common baseball oddID patterns:

• Batter hits over/under: batting_hits-PLAYER_ID-game-ou-over
• Total bases: batting_totalBases-PLAYER_ID-game-ou-over
• Pitcher strikeouts: pitching_strikeouts-PLAYER_ID-game-ou-over
• First 5 innings total: use the 1h period code

OddIDs follow the format {statID}-{statEntityID}-{periodID}-{betTypeID}-{sideID}. The full list is in the stats reference, and markets & coverage shows which books support what.

Baseball Player Props

Baseball props split cleanly between batters and pitchers, and we carry both in depth. On the batting side: hits, total bases, home runs, RBIs, runs, singles, doubles, triples, walks, stolen bases, strikeouts, hits + runs + RBIs, first home run and fantasy score. On the pitching side: strikeouts, outs recorded, earned runs, hits allowed, walks, pitches thrown and pitching win.

Props come back in the same response as the game lines and are identified by a single field, so filtering to only props — or excluding them — is one check. See the baseball player prop odds API for the complete market list by sport.

Baseball Odds API with Results

Odds and results arrive in one unified response, so you can settle bets without adding a second data source. Each response includes:

• Live and upcoming baseball games across every covered league
• Home and away team data
• Player statistics and box scores
• Full odds coverage — run lines, totals, moneylines, player props and alternate lines
• Final scores and settlement data

Line movement is tracked throughout, which matters more in baseball than most sports: totals and moneylines move sharply the moment starting pitchers are confirmed and lineup cards are posted.
