What is an Esports Odds API?
An esports odds API provides programmatic access to betting odds for competitive gaming events. These APIs cover major esports titles like League of Legends, Counter-Strike 2 (CS2), Dota 2, Valorant, Call of Duty, and others, delivering real-time betting lines from multiple sportsbooks for tournaments worldwide.
Esports betting is one of the fastest-growing segments in sports wagering. Esports odds APIs enable developers to build betting platforms, odds comparison tools, and analytics applications for this market.
Why Esports Odds APIs Are Different
- 24/7 markets: Esports tournaments run globally around the clock
- Rapid matches: Best-of-3 series can finish in 90 minutes
- Niche coverage: Not all sports odds APIs include esports
- Regional variations: Different games popular in different markets (LoL in Asia, CS2 in Europe)
- Live betting intensity: In-game rounds create constant betting opportunities

Esports Betting Markets
Match Winner (Moneyline)
Straightforward bet on which team wins the match or series. Most common market.
Map/Game Totals
Over/under on total maps in a best-of-3 or best-of-5 series. Popular for LoL, CS2, Dota 2.
Handicap/Spread
Map handicaps (e.g., Team A -1.5 maps) for lopsided matchups.
First Blood / First Kill
Which team gets the first kill in a map (LoL, Dota 2, Valorant).
Total Kills
Over/under on total kills in a map or match (common in MOBA and FPS).
Round Winner
Live betting on individual rounds in CS2, Valorant, R6 Siege.
Tournament Outrights
Futures bets on tournament winners (Worlds champion, TI winner, CS2 Major winner).
Player Props
Individual player performance: kills, deaths, assists, KDA ratios (limited availability).
Esports Data APIs: Match Stats, Live Scores and Player Data
An esports data API returns what happens in the game: results, scores and statistics. It carries no prices, so most betting and analytics products use it next to an esports odds API. A typical esports data feed covers:
- Match and map results: the series score, map or game winners, picks and bans, and side selection
- Live scores: the round score in CS2 and Valorant, or kills, towers and gold in League of Legends and Dota 2, updated while the game runs
- Player and team stats: kills, deaths, assists, damage, economy and objectives, per map and per series
- Rosters: current lineups, stand-ins and transfers, which change far more often than in traditional sports
- Patch versions: the game version of each match, because a balance patch can change which heroes, agents or weapons win
- Schedules and tournaments: brackets, stages, series formats (best of one, three or five) and start times
Official Data Against Scraped Data
Official data comes from the game publisher or the tournament organizer, usually through one licensed distributor per title or league. Riot Games, for example, names one official data partner for League of Legends and Valorant esports, and its rules for betting sponsors require official data. Official feeds read events straight from the game server, so they are complete, and regulated sportsbooks prefer them for settling bets.
Scraped data comes from public match pages, stats sites, broadcast overlays, or the game's own client and replay files. It costs less, and it often covers tier-2 and tier-3 events that no official feed carries. Expect gaps and delays, though. A stats site can block a scraper or change its layout without warning.
Latency follows the source. Tournament broadcasts run on a deliberate delay, so that teams cannot watch the stream for information about their opponents, and a feed built from the stream inherits that delay. Official server-side feeds usually push events within a second or two. That speed matters for live betting, where a late kill or round result leaves stale prices open. For a stats page or a post-match model, a feed that runs a minute behind is fine.
How a Data Feed Differs From an Odds Feed
The two feeds answer different questions. A data feed reports the state of the match: who won the pistol round, which team took the first tower, what the series score is. An odds feed reports prices for match winner, map handicap and total maps, and how those prices move. Neither one replaces the other.
Most products need both. A live betting app shows the score next to the price, and it needs results to settle bets. A prediction model trains on match stats, then compares its numbers with the market price to find value. An odds comparison site can start without a data feed, but it needs results as soon as it tracks closing line value or grades user picks.
If you buy the two feeds from different sources, budget time to match their event ids. Team names differ ("NAVI" in one feed, "Natus Vincere" in the other), and one feed can list a series as one event while the other lists each map.

It carries no betting prices, so betting and analytics products usually pair it with an esports odds API. Official data comes from the game publisher or the tournament organizer. Scraped data costs less, but it is slower and has more gaps.
Which esports do odds APIs cover?
Major esports odds APIs cover League of Legends (LoL), Counter-Strike 2 (CS2), Dota 2, Valorant, Call of Duty, Overwatch, Rainbow Six Siege, Rocket League, and mobile esports like Mobile Legends. Coverage varies by provider: some cover all of these titles, while others focus on top-tier games.

Yes, many esports odds APIs provide live in-game betting odds for CS2 rounds, LoL objectives, Valorant maps, and Dota 2 events. Some providers offer WebSocket connections for real-time esports odds updates. This guide to live sports odds APIs covers WebSocket feeds and latency in detail.
Are esports odds available for free?
Some providers offer limited free tiers (e.g., 500 requests/month) which include esports odds for major titles. This is sufficient for testing and small-scale projects. For production esports betting apps, paid plans typically start at $50-200/month. The free odds API comparison covers the free options.
Which API has the best esports coverage?
Some providers cover esports across 100+ sportsbooks and a wide range of games. For affordable options with good coverage, several providers include major esports titles in their standard plans. Check each provider's specific esports list in the SportsAPIs.dev directory.
Can I get odds for regional esports leagues?
Yes, most APIs cover regional leagues like LCS (North America), LEC (Europe), LCK (Korea), LPL (China) for LoL, and ESL Pro League, BLAST Premier for CS2. Coverage of tier-2 and tier-3 tournaments varies by provider, and international-focused APIs typically have better regional coverage.
Do esports APIs include player props?
Esports player props (individual player kills, deaths, assists) are rare and typically only available from premium providers or for major tournaments. Most APIs focus on match winners, map totals, and team-based markets rather than individual player performance.
Use the Esports filter in the SportsAPIs.dev directory to see which providers carry esports data, odds, or both.
