System
Every metric has an explicit origin. External NBA statistics and app calculations never masquerade as Sleeper fields.
League, rosters, matchups, player metadata, and observed NBA schedule and per-game history feeds. Schedules cache for 30 minutes; selected-player history caches for six hours and is re-scored using your league’s rules. The history feed is observed, not a documented API contract.
Free, no API key. Player bios, regular-season game logs, headline links, and highlight links. These are unofficial feeds with no availability guarantee; failures are shown separately from Sleeper data.
Calculated from Sleeper roster records and the selected week’s matchup payload.
Keeper plans are separated by league, linked team, and planning season. Shared hosting requires Discord sign-in and persistent server storage. Nothing is written to Sleeper.
ESPN player matching requires a unique normalized full name and a verified profile identity. Unmatched players keep their Sleeper profile. Bios cache for six hours, game logs for one hour, and headlines for 30 minutes. Source timestamps and individual feed failures appear with the content. Highlight links play on ESPN.
