Operators

Run an online casino?

Launch KOI games for your players with one authenticated call and settle every round against your own wallet.

Aggregators

Serve many brands?

Connect once and route sessions and callbacks for every operator brand you represent through a single KOI account.

Seamless wallet Your wallet stays the source of truth. KOI calls your bet, win, rollback and balance endpoints. Funds never leave your platform. Security Every callback is signed. HMAC SHA-256 over the exact URL and body, keyed by your access token. Reliability Safe to retry. Unique transaction IDs, resent unchanged on retries, let you apply every movement exactly once.
