How often does an NHL player go over his assists line?
One row per game with a player's assists line, the price, his assists and whether he went over. Nathan MacKinnon went over in 43 of 80 graded games.
Code verified October 21, 2026. One call to get_prop_history, 10 credits.
The call
player_id comes from search_players. Other markets: points, goals, shots on goal, blocked shots, goalie saves and anytime goal scorer. A game with no box score yet comes back with a null result and is left out of the rates.
