Return the live player-props board for NFL, MLB or WNBA (MCP Connect or Pro).
Requires ``Authorization: Bearer obmcp_...`` (MCP Connect — included with
website Premium — or MCP Pro). Free and anonymous callers are denied.
Each prop row carries: player, team, game, kickoff (America/New_York),
market, line, model projection, model over/under probability, the stored
best price and book (plus other books where the odds file stores them),
edge_pct, the model's pick side, confidence tier and units where the lane
produces them, whether it is on the lane's premium board, and
``lane_status`` — the factual verdict of that lane's promotion gate
(e.g. NFL ``research_board``, WNBA ``promoted_live``, MLB per market).
lane_status is information, not a filter: every row is returned.
Prices are exactly as stored by the odds pipeline; a missing price is
``null`` (never a placeholder). MLB rows come from the daily MLB props
export: the MLB ledger stores no pick side for player props, so
``pick_side`` is null and ``edge_pct`` is the stored OVER-side edge
(``edge_side: "over"``).
Args:
league: ``nfl``, ``mlb`` or ``wnba`` (required).
date: ``YYYY-MM-DD`` slate date in the live window — yesterday through
7 days ahead (America/New_York); defaults to today. Earlier dates
are resolved history: use ``get_player_prop_history`` (MCP Pro).
game: Optional matchup/team filter (e.g. ``"NE@JAX"``, ``"JAX"``).
player: Optional player-name filter (substring, accent-insensitive).
market: Optional market filter (e.g. ``rush_yds``, ``points``,
``pitcher_ks``).
limit: Max rows (1-200, default 100), sorted by edge_pct descending.
