Ask your AI for the better price.

• “Where is Kalshi cheaper than DraftKings on NFL passing yards right now?”
• “Give me tonight's five biggest NBA prop edges and name the venue on each.”
• “Has Kansas City beaten the spread more often than the market implies this season?”
• “Which MLB strikeout props are mispriced against the exchanges today?”

get_prop_edges

Player props where a prediction market or exchange is priced below de-vigged fair value right now, with the fair probability it was measured against and which sharp venue supplied it. Sports: NFL, NBA, MLB.

get_projection_picks

Player props ranked by the gap between our own projection and the price on offer, optionally narrowed to one venue (the same ranking behind the "best {venue} picks today" pages). Sports: NFL, NBA, MLB. Give a venue with no sport for that venue's CROSS-SPORT best bets — the board its /books/{venue} page publishes.

get_team_trends

How often a team has beaten the team-level betting markets this season: against the spread (run line for MLB), game total over, team total over, and moneyline — overall and split home/away. Sports: NFL, NBA, MLB.

get_odds_comparison

Live odds compared across every sportsbook AND every prediction market (Kalshi, Polymarket, Novig, ProphetX), ranked by how many percentage points of implied win probability the best available price gives back against the median of the other venues on the same outcome. A price comparison, not a view on who wins. Game moneylines, spreads and totals plus player props. Sports: NFL, NBA, MLB. Pass mode: "venue_quality" for a per-venue roll-up (best-price share, hold) on PLAYER PROPS ONLY instead of a per-outcome ranking.

get_arbitrage

Bets whose two sides can currently be backed at two DIFFERENT venues for less than a certainty — net of each venue's trading fee, both legs repriced within minutes of each other, both on the identical line. Usually returns nothing, which is the normal state. Sports: NFL, NBA, MLB.

get_vig_by_venue

What each sportsbook and prediction market is currently charging on player props: the median vig (how far a venue's two prices on the same prop sum above 100% implied probability), per venue and per prop market, measured off the live board. A cost-of-the-venue ranking, not a best-price-on-one-outcome ranking. Sports: NFL, NBA, MLB.

get_player_prop_prices

Player props with hit rates: all live prop markets for one player, current line, best price, every venue's quote, FTA's projection where one exists, and hit-rate windows (last 3/5/10/20 games and all available games) against the current line. Pass `query` (a player name) or `player_id`. Sports: NFL, NBA, MLB.

get_hit_rate_screener

Prop hit-rate screener: every player prop on today's board for one sport, at its main line, with the player's last 5/10/20 game Over and Under hit rates and the best price and book each way. Filter by market, position, side, window and minimum hit rate. Sports: NFL, NBA, MLB.

get_line_movement

Player props whose Over price or line moved most in a recent window (1h, 3h or 12h), one row per player and market at its main line: line, price and Over implied probability then vs now at every book, the change in likelihood in probability points, which book moved first, how many books followed, and the steam flag. Upcoming games only. Sports: NFL, NBA, MLB.

get_defense_vs_position_props

NFL defense vs position for player props: per-game stats every NFL defense has allowed to QBs (passing yards, passing TDs, completions, attempts, interceptions, rushing yards), RBs (rushing yards, rush attempts, receptions, receiving yards, total TDs) and WRs/TEs (receptions, targets, receiving yards, receiving TDs), over the last 5 games and the season, ranked 1 = allows the most. Also returns today's main prop line for players facing each defense. NFL only.
