Sportsbook API: sports betting through the same wallet as your casino

What you are actually integrating

"Sportsbook API" can mean three different products, and suppliers rarely say which one they sell:

• a raw odds API, a feed of prices you must turn into a betting product yourself, with your own trading, bet acceptance and settlement;
• a platform, where the sportsbook comes bundled with player accounts and payments you may not want;
• a managed sportsbook, where odds, markets, bet acceptance and settlement are handled inside the product, and you embed it and connect your wallet.

We supply the third. Nocturn Sport, the sportsbook in our catalog, arrives as a finished betting product: lobby, event pages, bet slip, live markets, settlement. Your work is to launch it and handle the money movements, exactly as you would for a slot. If your project needs a bare odds feed to drive a front end you have built yourself, tell us your use case before you plan around it.

How the betting API integrates

The sportsbook is an entry in the same game list as our 40,000+ casino games. You open it with the same launch call, passing the player, the device, the country and the language, and load the returned URL in an iframe or a full-page view. From then on, it talks to your wallet through the same three callbacks:

1. balance when the player opens the sportsbook,
2. debit when a bet is placed and accepted,
3. credit when a winning bet settles.

If your casino integration already works, sport works. That is the whole point: no second spec, no second set of credentials, no second reconciliation process.

The sport-specific details your wallet should expect

Casino rounds settle in seconds. Sports bets do not, and three consequences matter for your wallet code.

• Delay between debit and credit. A pre-match bet placed on Monday for a Saturday match is debited on Monday and credited on Saturday, if it wins. Your ledger must keep open bets as open, not treat them as failed rounds.
• Losing bets send no credit. A lost bet simply produces no further callback. Do not wait for a zero-amount credit to close it.
• Rollbacks happen. A cancelled or voided event can reverse a movement. As with casino games, it arrives flagged as a rollback and is handled as an ordinary debit or credit, protected by your de-duplication on the transaction id.

What players can bet on

The board covers mainstream sports with the markets their followers actually look for, rather than one generic winner line copied everywhere:

Coverage changes league by league with the calendar, so the event list your players see is always the live one rather than a fixed brochure number.

Esports betting

Esports is part of the same book. Counter-Strike 2, Dota 2, League of Legends and Valorant are covered, with markets such as match winner, map handicap, total maps and correct score. Esports bettors tend to be younger, mobile and heavily in-play, so two behaviors are worth knowing: live betting reopens between maps once the previous map is confirmed finished, and markets lock rather than accept bets when the match state makes a price unsafe. For operators in markets where esports is a large share of betting interest, that is often the difference between a sportsbook that feels current and one that feels like an afterthought.

Pre-match and in-play

Pre-match markets open well ahead of the event and close shortly before it starts. Live events stay on the board with the running score, and prices are re-quoted from the match state as play develops. When it is not safe to take a bet, the market locks instead of accepting a stale price. Settlement is automatic once the result is confirmed, and the credit callback follows.

The bet slip handles singles and combinations, shows the potential win before the player confirms, and can accept a better price automatically if odds improve while the bet is being placed.

Risk settings that protect a new book

Operators adding sport for the first time worry, rightly, about exposure. Stake and payout limits are set per sport and per market type. Combinations are capped at the strictest leg, so a long accumulator on a quiet league cannot carry a large payout. Thin markets carry more margin protection than headline fixtures, and two-way lines where one side would fall below a sensible minimum price are closed rather than offered. If your players concentrate on one league or one esports title, ask us about tuning the book for it. More on configuration is on the sportsbook software page.

Languages, currencies and mobile

The betting interface is translated into 32 languages, sport and market names included, with Arabic and Persian laid out right to left. Through the API, the sportsbook works in the same 38 ISO currencies as our main slot range, and the interface displays crypto denominations such as USDT, BTC (in mBTC or satoshis), ETH and TON with the right decimals. Your currency call shows what is enabled for your account. The mobile layout is designed for the phone first, with a bottom bar for sports, live, search, bets and the slip.

Front-end choices for your sport section

Because the sportsbook launches like a game, you decide how prominent it is. Some operators open it full-page from a "Sports" tab in the main navigation; others embed it beside the casino lobby or link to live events from a homepage banner. Pass the player's language and the correct device on every launch, so mobile players get the phone layout and the right market names. If you serve several markets, a separate brand per market, each with its own credentials and callback URL on the same account, keeps languages, currencies and featured leagues clean.

Cost

We take 12% of sportsbook GGR, deducted from the same prepaid credit as your casino commission. There is no separate license fee, setup fee or monthly charge for sport. See pricing for the full table.

Getting started

If you already have casino access, the sportsbook is in your game list. If not, request credentials on the API key page and follow the quick integration steps; the wallet work is the same. For the wider API, see casino game aggregator API, and compare sportsbook suppliers on our comparison hub.
