The platform

What is FastGamesAPI

A games supplier you plug in once.

FastGamesAPI is a remote gaming server (RGS): a full shelf of casino games delivered to your platform over a single REST endpoint, settled against your wallet over gRPC. You integrate one time — every title on the shelf, present and future, arrives through the same /api/v1/bet call and the same two wallet operations.

Uptime

01 / DELIVERY

One REST endpoint, one gRPC wallet

All 68 games run on the same pure-Go engine and resolve through /api/v1/bet. Your backend calls it; the RGS plays the round and settles. gRPC edge with per-operator IP allow-listing.

02 / CUSTODY

You keep the wallet — zero custody

Operator owns every balance. We never hold player funds. Money moves only through your wallet service, called back over gRPC + mTLS on every round.

03 / FAIRNESS

Provably fair, verifiable by anyone

Every outcome is HMAC-SHA256(server_seed, client_seed:nonce), committed before play and publicly checkable at /api/v1/seed/verify. The audit trail is the product.

04 / SPEED

Sub-3ms atomic settle

A full round-trip — debit, play, settle, both wallet ops included — clears in under 3ms. Pure Go, in-memory cache, ~150K req/sec/node at 99.9% uptime.

05 / RTP

Dynamic RTP, per game, per player

Set return-to-player 85–99% at game-init, snapshotted into every round, deterministic and never above 100%. Different players can run different RTP on the same integration.

06 / ANALYTICS

A metrics ledger, per round

Per-round GGR by game, currency, site and environment, with round forensics and real-time health. Reconcile any bet against your wallet with GetTransaction.

How it works

Why operators pick us

Math you can audit. Money you keep.

Certainty is the product: a fairness scheme anyone can verify, a wallet you never hand over, and an RTP that is bounded by design.

Provably fair · commit → reveal

01

Commit

Before play we publish sha256(server_seed) — the outcome is locked, not yet known.

02

Play

Your client_seed + a per-bet nonce feed HMAC-SHA256 to draw the result.

03

Reveal

After the round we reveal the server_seed; it must hash to the earlier commit.

04

Verify

Anyone re-checks the round at /api/v1/seed/verify — no trust required.

The wallet — two calls

Zero custody, atomic settle

You expose exactly two capabilities over gRPC + mTLS. Balances never leave your ledger.

GetTransaction — read a round back for reconciliation and dispute resolution.
Atomic SettleBet — ATOMIC_SETTLE_V1 debits stake and credits winnings in a single call, halving wallet round-trips on most games.

The margin — dynamic RTP

Bounded 85–99%, never over 100%

Set return-to-player per game at init; it is snapshotted into every round and is fully deterministic.

Per-game, per-player — different RTP on the same integration.
Per-currency, per-game bet limits enforced server-side.
Per-round GGR reporting by game, currency, site & environment.

Commercials

Two ways to buy

Pricing set per operator — your call.

Pick the model that fits your book. Both come with the full integration, the same games and the same settle. Admin-set per operator, switchable as you grow.

Model A

Flat platform fee

A granted game set at a fixed monthly cost. Predictable spend, and you keep the full margin on every round you take.

Fixed cost — budget with no surprises.
Full margin — the house edge is entirely yours.
Granted game set — the titles you choose, live.
Best when volume is steady and known.

Model B

GGR revenue share

A low fixed base plus a share of gross gaming revenue, reported per round. Costs stay small early and scale only as you win.

Low fixed base — start light.
Per-round GGR reporting, fully transparent.
Scales with growth — pay in step with revenue.
Best when you're ramping volume.
