The ownership that the contest's own lineups show, without the lineups. One row per player and roster slot, from the lineup file of this contest only. The answer never reads another contest and never falls back to the slate.

Slots. A classic contest has no slot: slot is null and the row holds the share of lineups with the player in any seat. A single-game contest has one row per player and seat kind: CPT (DraftKings captain) or MVP (FanDuel), and FLEX. The CPT or MVP rows sum to 1.0 and the FLEX rows to the number of FLEX seats of the format (5 on DraftKings Showdown), each less the share of seats for which the lineup file names no player (a placeholder seat of the operator's file): a FLEX sum can read 4.82 to 4.98. position is the natural position of the player on every row. total_ownership is the player's share in any slot.

Basis. actual_ownership is lineups / lineups_used as a ratio from 0 to 1 with 4 decimals (0.2213 is 22.13%). lineups_used is the number of lineups the ownership was computed from and entry_count is the entry count the operator lists, so a customer sees whether the capture is complete. A player in no lineup has no row.

Records. On a plan that meters routes (Pro, Elite) one call costs 1 record for every 100 lineups of the contest (lineups_used), at least 5 records, whatever the number of rows it returns and whatever the filters. A contest with 30 lineups costs 5 records, one with 190,357 lineups costs 1,904, and the largest (about 950,000 lineups) costs 9,496. An empty answer costs 1 record, the minimum of every metered request. A caller without DFS access (no key, a Free or Starter key) reads 5 rows and is charged for the rows it gets. A marquee contest (GET /api/v1/dfs/marquee) is open in full: its ownership is one row per player, not per entry.

Reading the values. actual_ownership has 4 decimals. A player held by 1 of 190,357 lineups reads 0.0000 with lineups = 1, so use lineups / lineups_used or filter on lineups. position is the operator's token: DST on DraftKings, D on FanDuel. The slot filter takes CPT on DraftKings, MVP on FanDuel and FLEX on both single-game formats. A classic contest has no slot, so slot=FLEX returns no row there.

Empty answer. The answer is 200 with no rows and a reason. contest_not_final: the contest is not final. in_game_format: the contest is on an in-game format (second half, fourth quarter, in-game Showdown), which has no ownership table. no_lineups: the lineup file of the contest holds no lineup. league_not_computed: the actual ownership of the contest's league is not computed (MLB, NHL, golf; NFL and NBA are). actuals_not_recomputed: the ownership of the contest is not yet computed from its lineup file.
