Sports prediction API pricing.

Model win probabilities for eight public API sports: NBA, WNBA, NCAAMB, NCAAWB, CFB, NFL, NHL and MLB. Public benchmark artifacts document selected evaluations, and our filtered public results ledger includes wins and losses. Compare fair value with prices across Polymarket, Kalshi and sportsbooks before you act.

Public benchmark evidence. The results page reports measured execution-ID and direct-tx-hash coverage.

Monthly Starter through Stripe: if the 7-day trial ends without a payment method, access ends with no charge. With a saved or added payment method, it renews at $49/month unless you cancel first.
