Getting Started with the Sports Game Odds API
Whether you’re building a sportsbook, fantasy sports app, betting model, or analytics dashboard — the Sports Game Odds API gives you the data and odds you need to power your platform with precision.
Our odds API delivers live and pre-match odds, player props, game props, scores, results, and historical data across 25+ sports and 55+ leagues — all updated at sub-minute intervals.
Overview: How SportsGameOdds Works
The Sports Game Odds API gives developers fast, structured access to global betting markets via secure HTTPS requests. Every response is returned in clean JSON format — ideal for modern web and mobile apps.
Each endpoint (such as /events, /odds, or /teams) has its own parameters and response structure. Full documentation — including code samples — is available in the API Reference.
All requests must include your unique API key in the header:
x-api-key: YOUR_API_KEY

Whether you’re analyzing betting markets, building a DFS optimizer, or creating visualization dashboards — you’ll have all the building blocks in one place.
Fetching Data in Batches
For high-volume endpoints such as /teams, /events, and /odds, responses are paginated to improve performance. Use the limit parameter to control how many results are returned (default 10, max 100), and the cursor parameter to fetch additional pages.
Example: Fetch All Finalized NBA Events (JavaScript) let nextCursor = null; let eventData = [];
do { const response = await axios.get(‘/v2/events’, { params: { leagueID: ‘NBA’, startsAfter: ‘2024-04-01’, startsBefore: ‘2024-04-08’, limit: 50, cursor: nextCursor } });
const data = response.data; eventData = eventData.concat(data.data); nextCursor = data?.nextCursor; } while (nextCursor);
Once you have the data, you can feed it into your betting model, database, or dashboard.
SportsGameOdds: Handling Odds & Results
Every event in our system includes both odds data and final results, so you can easily grade bets or train models.
Example: Parse and Grade Over/Under Odds
eventData.forEach((event) => {
const odds = event.odds;
Object.values(odds).forEach((oddObject) => {
const { oddID, score, closeOverUnder } = oddObject;
if (score > closeOverUnder) console.log(${oddID} - Over Wins);
else if (score === closeOverUnder) console.log(${oddID} - Push);
else console.log(${oddID} - Under Wins);
});
});
This allows for automated settlement or performance validation on your end.
Fetching Teams with SportsGameOdds API
You can fetch team details by league, sport, or specific team ID.
Example 1: Fetch a Specific Team await axios.get(“/teams”, { params: { teamID: “LOS_ANGELES_LAKERS_NBA” } });
Example 2: Fetch All NBA Teams await axios.get(“/teams”, { params: { leagueID: “NBA” } });
Example 3: Fetch All Basketball Teams await axios.get(“/teams”, { params: { sportID: “BASKETBALL” } });
All responses are structured JSON objects including team colors, names, and identifiers.
Improving Response Speed
We’re continually optimizing our infrastructure and adding parameters to let you request only the data you need. A GraphQL API is also on our roadmap for more flexible querying.
Tips for Faster Responses with SportsGameOdds API
Use oddIDs to fetch only specific odds.
Include includeOpposingOddIDs=true to also return opposite sides.
Replace the player portion of an oddID with PLAYER_ID to query multiple players at once.
Example:
oddIDs=batting_strikeouts-PLAYER_ID-game-ou-under includeOpposingOddIDs=true
This returns both Over and Under odds for all player strikeout markets in your query.
