Casino gaming API for South Korea

Casino gaming API in South Korea: what you actually get

GamingAPI is a casino games aggregator for South Korea. One integration — a single API key, a single secret and one callback URL — connects your brand to 16,000+ games from 150+ certified studios. You never sign a contract per studio, never run a separate wallet per provider and never maintain a second integration when a new studio launches.

The catalogue for South Korea spans slots, live dealer, crash and instant-win, table games, fishing/arcade, lottery, bingo and virtual sports. Operators here get the most traction from Evolution, Pragmatic Play, Habanero, with titles such as Baccarat, Speed Baccarat, Sic Bo, Sweet Bonanza in constant rotation.

How many games and which providers are live for South Korea

Roughly 14,000 of the 16,000+ titles are slots, with around 900 live dealer tables, 400+ crash and instant games, 600+ table games and 300+ fishing and arcade titles. Every game returns metadata through one endpoint: game code, studio, category, RTP band, volatility, thumbnail, supported languages, demo availability and mobile support.

Studios most requested in South Korea include Evolution, Pragmatic Play, Habanero, alongside Evolution, Pragmatic Play, PG Soft, JILI, Spribe, Ezugi, Habanero, CQ9, JDB, Fa Chai, Hacksaw Gaming, BGaming, Play'n GO, NetEnt, Amusnet, Nolimit City, 3 Oaks and Turbo Games. New studios are added to the same catalogue endpoint — no code change on your side.

KRW wallet, bets and balance accuracy

The integration is a seamless wallet: your platform stays the single source of truth for player balance. When a player opens a game we call your wallet for the balance, and every bet, win, loss, refund, bonus and jackpot event is delivered to your callback URL signed with HMAC-SHA256 within milliseconds of the round settling.

Every transaction carries a unique serial number and is idempotent at database level, so a duplicate callback can never move the balance twice, and a late win arriving after a session closes is still applied. Balances are auto-reconciled against the provider's own figure, so the number in the game and the number on your South Korea site always match.

Payments and settlement for South Korea operators

Your player cashier stays yours: Bank transfer and crypto deposits are handled on your side in KRW. GamingAPI only settles the B2B side — your GGR wallet is topped up with USDT (TRC-20, minimum 15 USDT, roughly ₩20,000) and GGR is deducted automatically per settled round.

Billing is loss-only: commission applies to positive GGR, never to rounds the player wins. Reports in the client panel are shown in KRW, and invoices are issued in USD/USDT. Game launch is blocked below roughly ₩1,100 so you are never exposed to unbilled play.

Working in KRW: rates, rounding and limits

The wallet is native KRW (South Korean Won) — assigned when your account is created and fixed afterwards, so historical reports never shift under you. There is no conversion step inside a round: the stake leaves the player wallet in KRW and the win returns in KRW, which is why the figure in the game and the figure on your site agree to the last digit. KRW has no minor unit, so stakes and payouts are held as whole units.

Commercial terms are quoted in USD and converted at the reference rate of roughly 1,400 KRW per USD: the one-time setup is $350 (about ₩470,000), the monthly platform fee is ₩0, and there is no FX markup, per-call fee or refund fee. Typical stakes run from about ₩140 to ₩680,000 per round depending on the game, and per-game, per-player and daily limits are configurable from the client panel.

Settlement follows a UTC+6 (daily cut-off 00:00) day. GGR is deducted per settled round in KRW, the weekly statement closes on Monday, and the balance is payable in USDT within 48 hours. Because commission only applies to positive GGR, a losing week for the platform costs you nothing.

Going live in South Korea

Sandbox credentials are issued the same day you ask. A typical South Korea operator integrates the launch endpoint and wallet callback in 2–5 days, tests bet/win/refund and duplicate handling in sandbox, then switches to production keys — most brands are live within 5–7 days.

You keep full control of front-end, lobby layout, bonuses, limits and reporting. Licensing, responsible gaming tooling and jurisdiction rules are configurable per brand, and 24/7 Telegram support (@CasinoxApix) covers integration and live incidents.
