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 73.3% across 80,378 backtested calls.

Cheaper than building it. Sourcing fixtures and odds, normalising them across eleven sports, fitting and calibrating a model, then keeping the whole thing live and fresh is weeks of engineering and a standing maintenance cost. Pro is $49/mo — request a key and skip the build entirely.

*Redistribution rights cover our own derived outputs (probabilities, Elo ratings, calibration) where upstream data licensing permits. Overage is metered, not punitive; the Free tier has no overage — it stops cleanly at 250.

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.

Honest by design

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 signal or a profit promise.

No profit or accuracy guarantee. These are calibrated probabilities from out-of-sample backtests, not predictions of profit, and not betting or financial advice. Past and simulated performance is not a reliable indicator of future results. For information and entertainment only.

Questions

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 250.

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 a betting signal. The SLA covers availability and freshness only, never accuracy. For information and entertainment only, not betting, investment or financial advice.
