INDEPENDENT DEVELOPER REFERENCE
How far back does the historical data go?
Recording began around 2026-11-03. Retained history is short, and it is not a complete opening-to-close archive. It does not contain seasons of past lines, and there is no public graded-results endpoint. Statistics samples can describe older games, but they were captured later.
Editorial review: · Not a live coverage report
Why old games do not extend line history
Independent ESPN statistics cover NBA, NFL and NHL as limited retained game samples, not full seasons. As of 2026-11-03 those samples were captured after the games were played, so they do not show what was known at game time. A box score from an older game does not bring a line with it. Read historical data for how to build your own archive from today forward.
