Frequently Asked Questions.

Koefy aggregates odds from licensed third-party providers and, where available, direct bookmaker feeds. We normalize markets into a consistent format so you can compare prices across bookmakers.

Odds refresh approximately every 60 seconds. Some events may update faster or slower depending on market activity and provider availability. Odds can change between refreshes.

We cover ~70 bookmakers across regions. Supported regions include United States, United Kingdom, Europe, Estonia, France, Sweden, and Australia. Coverage varies by sport, event, and bookmaker.

No. Koefy is an analytics tool. We don’t place bets, hold funds, or act as a bookmaker.

Yes. We’re expanding coverage over time — adding more markets, sports, and integrations. Availability depends on region, bookmaker offering, and data access.
