Assemble the whole story of a single prop in one call. Read-only. No side effects. Rate-limited per your tier. Pro tier and above; free/starter keys get a structured tier_required deny. No picks, no advice -- a data feed. Returns { found, sport, player, market, event, book:{line,source,odds}, flash:{line,rawBaseline,method,sampleN,sampleStrength,mode}, gap, gapPct, form:{n,recentMean,median,stdev,min,max,hitRateVsBookLine,hitRateVsFlashLine,recent}, splits, modeSplit, opponentSplit, recentMaps, movement:{openedLine,currentLine,delta,series?}, freshness:{contextGeneratedAt,ageHours,stale,observedThrough,observedAgeHours,observedStale,note}, missingReasons, disclaimer }. freshness splits two clocks: ageHours/stale is the pack BUILD age; observedThrough/observedAgeHours/observedStale is the real age of the form data (can be far staler if ingest froze), with `note` a human "Form data through <date>" line. hitRateVsBookLine is how often recent maps went over the POSTED line (what a bettor asks); hitRateVsFlashLine is vs the Flash projection. The movement point series is Pro-only (free gets opened/current/delta). Available for sports with a registered Flash pack (CoD and MLB today); other sports return found:false with a reason, never fake data. Every absent section carries an explicit missingReason instead of being silently dropped. When to use: to explain or justify one prop end-to-end (why the Flash line sits where it does, how the player has trended, whether the line moved). When not to use: for a broad market view use scan_props; for a player overview use get_player_context.
