Methodology

Every Kalshi quote is pulled directly from Kalshi's public REST API. Sportsbook lines come from The Odds API. We expose only computed fields (implied probabilities, de-vigged consensus); raw per-book prices are available in the interactive UI but not in this export to keep the payload bounded.

Full math + edge calculation documented at /about/methodology.

Limitations

• Hourly cache. For live data, use the interactive site or contact us for higher-frequency access.
• Top-N truncation — golf returns top 30 players; sports return next 20 games per league.
• Game-type events only in the sports section. Futures, awards, conferences, divisions etc. are queryable via the interactive site but not in this export.
• Stale references (>30 minutes old) are filtered out, so a freshly-restarted league may temporarily show empty events.
