Sportsbook APIOverview

Sportsbook API

The Sportsbook API is a suite of RESTful and WebSocket APIs for building your own sportsbook frontend on top of the GR8 Platform. You own the interface; the platform supplies the line and odds, the player context, bet placement and settlement.

Integration in 3 steps

1. Drive your frontend from the GR8 API

GR8 API (requires sign-in) is the user-context API your application talks to: line and odds, event content, bet placement, bet history, player settings. Every request carries your brand’s API key and, for a signed-in player, their access token — so responses come back already personalized for that player and brand.

For real-time line, market and score updates, connect the DirectFeed API (requires sign-in) (SignalR over WebSockets) rather than polling the line endpoints.

2. Connect your wallet

Required as soon as you accept real bets. Betting transactions run against your wallet: the platform calls endpoints you implement to read balances and to debit and credit players.

Wallet integration is documented in its own section, because the contract is identical for iFrame and Sportsbook API clients. Start with the seamless wallet — it is the recommended model.

3. Add server-to-server calls where you need them

S2S API is the service-context API for your backend: player registration and profiles, bet history and settlement, bonuses, limits, and line data outside a single player’s session. Optional — add it when your backend needs to act without a player request behind it.
