Nucleus Gaming API Integration Guide (2026) — Games, Wallet & Pricing
Sep 13, 2026 · 9 min read · Slots
Nucleus Gaming is a slots game studio with 90+ live titles, distributed to licensed operators by GamingAPI — a casino API provider serving 16,000+ games from 150+ studios through one REST API, one seamless wallet and positive-GGR settlement. If you searched for the Nucleus Gaming API, this page is the shortest path to it.
What is the Nucleus Gaming API?
The Nucleus Gaming API is the game-delivery interface that returns a signed launch URL for a Nucleus Gaming title and then calls your wallet for every bet, win and rollback inside that round. Nucleus Gaming is known for high-volatility slot mechanics, buy-feature titles and mobile-first portrait play. Through GamingAPI you consume that studio behind a single aggregator contract instead of negotiating, certifying and maintaining a direct studio integration.
How to integrate Nucleus Gaming in 3 days
- Request sandbox credentials and whitelist your server's fixed egress IP.
- Pull
/gamesand filterprovider = "Nucleus Gaming"to import 90+ game codes, names and thumbnails into your lobby. - Expose four wallet callbacks — balance, bet, win, rollback — with HMAC verification and idempotency keyed on the provider transaction ID.
- Call
/launchwith the game code, player ID, currency and language; open the returned URL in the player's browser or app webview. - Certify callbacks, switch to production keys, reconcile GGR daily.
Wallet flow for Nucleus Gaming rounds
Every Nucleus Gaming round follows the same contract as the rest of the catalogue: a debit when the round opens, one or more credits when it settles, and a rollback if the round is voided. Because the aggregator normalises the payload, you never write studio-specific wallet code — a Nucleus Gaming bet and an Evolution bet reach your endpoint in the same shape.
Nucleus Gaming in LatAm and other markets
Nucleus Gaming performs strongly in Brazil, Peru, Chile, Mexico, and GamingAPI settles those markets in local currency with positive-GGR billing, so you are charged only when the studio actually generates margin. Geo-restricted titles are flagged in the game list, so your lobby never shows a game a player cannot open.
Nucleus Gaming API pricing
No per-studio licence fee and no setup fee per provider. One revenue share on positive GGR covers Nucleus Gaming and every other studio on the platform, which is why adding a studio to your lobby is a configuration change rather than a commercial project.
Frequently asked questions
How do I get the Nucleus Gaming API?
You do not sign a separate contract with Nucleus Gaming. Connect once to the GamingAPI aggregator REST API and Nucleus Gaming is enabled on your operator account. The game list, launch URL and seamless wallet callbacks are identical for every studio, so the same integration serves all 150+ providers.
How many Nucleus Gaming games are there?
90+ live slots titles from Nucleus Gaming are available through GamingAPI, synced automatically as the studio releases new games.

Sandbox keys are issued immediately and most operators finish wallet-callback testing and go live with Nucleus Gaming in about 3 days.
Is Nucleus Gaming available in my country?
Nucleus Gaming is distributed through GamingAPI to licensed operators in 120+ countries, including Brazil, Peru, Chile, Mexico. Some titles are geo-restricted by the studio; the game list returns the allowed markets per game.
What does the Nucleus Gaming API cost?
There is no per-studio licence fee. GamingAPI charges a single revenue share on positive GGR (bets minus wins) covering the whole catalogue, so adding Nucleus Gaming costs nothing extra up front.
