Can I cancel anytime?

Yes — manage your subscription via the customer portal. Cancellation is immediate; you keep access through the end of the current billing period.

Can I have both a UI subscription and the API add-on?

Yes — they're independent. Subscribe to Pro for the web app + the API add-on to build on the data. Two separate Stripe subscriptions, billed independently.

What sports are covered?

PGA Tour golf, NFL, NBA, MLB, NHL, EPL, MLS, UEFA Champions League, FIFA World Cup — nine sports. Kalshi quotes refresh every 5 minutes; sportsbook lines every 15-30 minutes; Polymarket every 15 minutes; DataGolf model every 10 minutes.

Does SportsBookISH accept bets?

No. SportsBookISH is an information service — it shows you where prices differ across Kalshi, Polymarket, and licensed sportsbooks. You place bets at the books, on Kalshi directly, or on Polymarket directly.
