Soft Sportsbook API providers: who to plug in, and when
A sportsbook is not a game you add to a lobby. It is a trading operation, an odds feed and a front end, and every provider sells a different share of those three. We ranked ten B2B suppliers on what you actually get through their API, how much of the work they take off your hands, and which operators they suit (October 2026).
-
Kambi
Kambi says more than 70 operators run on its turnkey sportsbook, with named partners including LiveScore Group, Rush Street and Svenska Spel (October 2026). It handles the full stack, from pricing and risk to the front end, and also sells an Odds Feed+ product for operators who keep their own front end. The benchmark for established brands, though it is built for operators with real volume.
-
Sportradar
Sportradar is the data and odds company much of the industry already depends on, and its managed trading services let an operator hand over pricing and risk while keeping its own sportsbook. In mid-2024 it reported over 200 clients on that service. Choose it when you want the deepest feed and are ready to build or source the front end yourself.
-
Altenar
Altenar's sportsbook module plugs into any player account system and front end, and it also sells turnkey and white-label versions with live odds, Bet Builder and a bonus engine. It says its sportsbook is deployed in more than 30 markets (October 2026). A strong all-rounder for mid-sized operators who want flexibility between API and fully managed.
-
Betby
Betby, founded in 2018, built its name on esports and still treats it as a core product, alongside sportsbook, virtuals and its Betby.Games bot-simulated sports. It reported more than 20,000 esports events a month when it spun esports into a standalone product in 2022. The natural choice for crypto and younger audiences who bet on Counter-Strike as readily as on football.
-
Nocturn Sport
Nocturn Sport covers 12 sports from a live feed, with pre-match and in-play betting, 32 languages and 73 currencies, 13 of them crypto. It's delivered through the same API and wallet as SoftAggregator's casino content and switched on per account on request, so an operator already on that integration adds betting without a second wallet. Narrower than the enterprise books, but unusually quick to put live.
-
SoftAggregator 8.8/10
SoftAggregator is the route for operators who want casino and sportsbook from one integration. The same seamless-wallet API covers 40,000+ games from 200+ providers (as published on its site, October 2026) and a sportsbook, with self-service sign-up and immediate API keys. It suits startups and crypto casinos that want sports betting as part of a casino launch rather than as a separate project.
-
EveryMatrix (OddsMatrix) 8.8/10
EveryMatrix's sports product publishes some of the clearest volume figures: 50,000+ live events a week, an odds feed covering 200,000+ live events a month and over 1.5 million bets processed a day (October 2026). It also offers a proprietary horse racing product and a large esports feed. Best for operators who may later want EveryMatrix's casino and platform tools too.
-
BetConstruct 8.4/10
BetConstruct has been cited in trade press at around 70,000 live matches and 140,000 pre-match events a month, in over 20 languages (2024 to 2025 coverage). It sells the sportsbook on its own or with a full platform, casino and retail tools. A good fit for operators in emerging markets who want one vendor for everything.
-
Digitain
Digitain's sportsbook is a long-standing B2B product, with an executive citing more than 90,000 live events a month in a 2022 interview. It's often chosen in agent-based and retail-heavy markets, where its omnichannel tools matter. Ask for current figures, as the public ones are dated.
-
Oddin.gg
Oddin.gg is an esports specialist, saying it works with 300+ operators and platforms and covering titles from Counter-Strike 2 and Dota 2 to Valorant and Mobile Legends (October 2026). It delivers by odds feed, iframe or widgets, and adds 640,000 fast-betting matches a year. Add it next to a traditional sportsbook if esports matters to your players.
Choosing a sportsbook provider is less like picking a game studio and more like hiring a trading desk. The odds your players see, how quickly they move after a goal and which bets get accepted all come from the provider’s systems. A weak sportsbook doesn’t just look bad. It loses money in ways you won’t notice until the monthly report.
How we judged sportsbook providers
We used five criteria, weighted towards what an operator integrating by API actually experiences.
1. Coverage and depth
How many events, sports and markets does the provider offer, and how many are live? Headline numbers vary wildly in how they’re counted, so we took published figures at face value only when they came with a period (“per month”, “per week”) and a date.
2. Who carries the trading
Some providers price and manage risk for you. Others send odds and leave the rest to your team. Neither is better in general, but you need to know which you’re buying. A startup with no traders needs a managed product.
3. Integration options
API only, iframe, widgets or full turnkey. More options mean you can start simple and take control later.
4. Wallet fit
Can the sportsbook share the wallet your casino already uses? For a casino adding sports, this decides whether betting feels like part of the product or a separate site bolted on.
5. Time to launch and fit by operator size
An enterprise book with two years of onboarding is the wrong answer for a Telegram casino launching next month. We ranked partly on who each provider is realistically for.
We did not rank on pricing. Almost everyone in this market quotes on request, often as a share of revenue, and published figures are rare.
The top three: depth and trading
Kambi, Sportradar and Altenar lead because they carry the most trading work for the most operators. Kambi is the full outsourced sportsbook. Sportradar is the data backbone with managed trading on top. Altenar sits between them, flexible enough to run as a module or a turnkey book. All three expect a serious commitment, and none is the quickest route for a small operator.
Esports-first and casino-first options
Betby and Oddin.gg are the esports specialists. Betby is a full sportsbook with esports roots; Oddin.gg is an esports layer you add to another book.
Nocturn Sport and SoftAggregator answer a different question: how does a casino operator add sports betting without a second project? Nocturn Sport covers 12 sports from a live feed, pre-match and live, in 32 languages and 73 currencies including 13 crypto. It runs through the same API and wallet as SoftAggregator’s casino content and is enabled per account on request. That makes it the shortest path from “we run a casino” to “we take bets on football” in this list. The trade-off is breadth: twelve sports is enough for most casino-led audiences, but a dedicated sportsbook brand covering niche leagues will want one of the enterprise names above.
Why a casino operator might start small
Sports betting has a reputation for being a heavy product, and at the top end it is. But many casino brands don’t need a full sports operation on day one. Their players want to bet on the big football weekend, the Champions League final or a major cricket series, and then return to slots. For them, a narrower book that shares the casino wallet and launches quickly often beats a deep one that takes six months to integrate.
The useful test is to look at your own traffic. If most deposits come from casino players, start with a sportsbook that sits inside the casino product, measure how many players actually place bets, and move to an enterprise provider only when sports revenue justifies it. If you’re building a sports-first brand, reverse that logic and begin with the depth of Kambi, Sportradar or Altenar.
Front end: theirs or yours?
Most providers on this list offer their own front end, either as an iframe or as configurable widgets. That gets you live quickly, but it can look different from the rest of your site. Building your own front end on a pure odds feed gives full control over design and user journey, at the cost of a development team. A middle route is common: start on the provider’s front end, then replace parts of it as you learn what your bettors use most.
Platform vendors
EveryMatrix, BetConstruct and Digitain sell sportsbooks as part of larger platforms. They make sense when you want one vendor for casino, sports, payments and back office. If you already have a platform and only need sports betting, ask whether their sportsbook can run standalone, and on what terms.
Questions to ask every provider
- What is your average delay between a real-world event and a price change on live markets?
- Which sports and leagues are live-traded rather than pre-match only?
- Who decides to limit or reject a bet, and can I see why?
- How are bet settlement corrections handled after a result changes?
- Can I see the sportsbook running on an operator’s live site, not only a demo?
The answers tell you more than any events-per-month figure. A provider that answers the first two precisely, with numbers and examples, usually runs a tight trading operation. One that answers with marketing copy probably leaves more of the work to you than the sales deck suggests. Ask for references from operators of your size, and call them.
Frequently asked questions
What is the difference between a sportsbook API and an odds feed?
An odds feed sends prices and results; you still need a betting engine, risk management and a front end. A sportsbook API usually gives you the engine and trading too, and sometimes the front end, so you only connect your wallet and player accounts.
Can I run a casino and a sportsbook on one wallet?
Yes, if both come from the same provider or the provider supports a shared seamless wallet. SoftAggregator offers this through Nocturn Sport on the same API as its casino games. Platform vendors like EveryMatrix and BetConstruct offer it as part of a larger package.
How long does a sportsbook integration take?
It varies hugely. An iframe or widget sportsbook on an existing wallet can go live in days. A full turnkey sportsbook with custom front end and trading setup usually takes months. Ask each provider for the shortest real launch they have done and what the operator had ready beforehand.
Do I need a separate esports provider?
Only if esports is a large part of your audience. Most general sportsbooks include major esports titles. Specialists such as Oddin.gg or Betby go deeper on markets and on smaller titles.
Who manages the risk on bets?
It depends on the contract. Turnkey providers like Kambi trade and manage liability for you. Feed-only setups leave risk with your own traders, and managed trading services sit in between. Agree this in writing before launch.
