Data sources and attribution

Policy version 2026-11-08 · Private pilot draft

ESPN

Schedules, scores and available research context come from ESPN’s public, undocumented feeds. These endpoints may change or stop working. Displayed fetch times describe when FieldBet received the response, not when the provider last changed it.

Kalshi

Matched winner-contract prices come from Kalshi’s public API. YES asks are reference buy prices; YES bids are reference sell prices. FieldBet sends no exchange orders and has no claimed affiliation or endorsement. Source timestamps, when supplied, remain distinct from fetch times. Stale prices are shown for reference and cannot be used for new entries.

Optional injury context

SportsDataIO injury context is used only when configured with live entitlements. Trial data does not replace factual injury reports. Attribution and coverage warnings accompany research. Team names and provider marks belong to their respective owners.

Attribution does not establish a license. Public display, caching, historical retention and derived-model uses still require review of each applicable agreement before launch. Premier League fixtures can be browsed; executable winner prices are unavailable where no verified contract mapping exists.
