How to choose a casino API provider
Every aggregator claims thousands of games and a fast integration. These are the twelve checks that actually separate them — most can be verified in a sandbox before you sign.
Catalogue: depth versus verified depth
A game count is a marketing number. What matters is how many of those titles genuinely open for your players, in your market's currency, today. Ask the supplier to demonstrate a launch in your currency for the specific studios you care about — not a demo in EUR.
AS Tech API runs real launch probes per currency and per provider, and the back office lists the studios verified to open in each one. That is why the supported-provider count differs between, say, INR and PYG: it reflects what actually works rather than what is theoretically listed.
- Number of providers and titles — then verified counts in your currency
- How often the catalogue syncs and whether new releases appear automatically
- Whether live casino, sportsbook and mini games are in the same contract
- Whether provider categories are normalised for your lobby
Technical fit
The integration surface should be small and documented. Ask for the docs before you talk price — the quality of the documentation predicts the quality of the integration more reliably than any sales call.
- Seamless wallet support with signed, idempotent callbacks
- One authentication scheme across all providers
- Sandbox with the full catalogue, not a sample
- Working client libraries and a hosted API tester
- Round-level history with the raw callback payloads retained
Operations and reporting
You will live in the back office far longer than you will live in the integration. Check that you can answer a player dispute in under a minute: find the player, find the round, see the stake, the payout, the provider response and the exact callback that settled it.
- Session and round drill-down with per-round GGR
- Player management and transaction ledger
- API error logs visible to you, not just to the supplier
- GGR statements you can reconcile against your own ledger
- Sub-account or reseller hierarchy if you serve other brands
Commercial terms
Get the blended rate, not the headline rate, and ask directly about minimum guarantees, setup fees and security deposits. A flat rate across all providers removes an entire negotiation and makes forecasting trivial.
- Flat versus per-provider revenue share
- Setup fee, security deposit, minimum monthly guarantee
- Settlement frequency and prepaid versus invoiced billing
- Notice period and what happens to your data on exit
Red flags
Three warning signs are worth walking away over: a sandbox that only shows a handful of demo games, refusal to show round-level history before signature, and a currency answer of 'it should work' rather than a verified launch in front of you.
Frequently asked questions
What should I look for in a casino API provider?
Verified game availability in your currency, a seamless wallet with signed idempotent callbacks, a full-catalogue sandbox, round-level reporting you can audit, and transparent flat commercial terms without hidden minimum guarantees.
How many game providers do I actually need?
Far fewer than the headline counts suggest — a strong lobby is usually built on twenty to forty studios that perform in your market. What matters is that the aggregator can add more without another integration.
Should I use one aggregator or several?
One is simpler to reconcile and cheaper to operate. Operators add a second only for exclusive content a primary supplier genuinely cannot carry.
