Pay for probabilities
that mean what they say.
Every plan reads the same calibrated, multi-sport probability API. You pay for request volume, sport coverage and the depth of each response — and every tier can verify the numbers itself at /v1/accuracy. See how reliable they are on the calibration page: say 70–80% and it won 75.3% across 67,667 backtested calls.

What each tier includes.
Same API, same honest numbers. The plan only changes how much you can call and how deep each response goes.

Request caps are monthly soft limits. The availability SLA covers uptime and freshness only — never accuracy. There is no accuracy or profit guarantee on any tier.
What your money buys.
Clean, calibrated, multi-sport probabilities with the rationale behind each one, and a published track record you can audit straight from the API. A well-calibrated 60% pick wins about 60% of the time — that makes the probabilities reliable, which is the whole point. What it is not is a betting edge or a profit promise.

Pricing FAQ.
What counts as a request?
Every successful GET to a /v1/* endpoint counts as one billable request. Cached 304 responses and /v1/health are free. Pagination means one page is one request, so you only pull what you need.
How does overage work?
Past your monthly cap, extra calls are metered at $1–$2 per 1,000 (Business $1, Pro $1.50, Dev $2). The Free tier has no overage — it stops cleanly at 500.
Can I change or cancel my plan?
Yes — upgrade, downgrade or cancel any time. Changes take effect next cycle, and you keep access until the period you have paid for ends.
Do you guarantee accuracy or returns?
No. We publish our hit rate, calibration error and the full reliability table openly — including the tiers where the model is barely better than a coin-flip — precisely so no one mistakes calibrated probabilities for an edge. The SLA covers availability and freshness only, never accuracy. For information and entertainment only, not betting, investment or financial advice.
Start on the free tier, no card required.
Read calibrated probabilities, fixtures, Elo ratings, accuracy and the backtest from one schema. Upgrade only when your volume or depth needs it.
