PropLine — Sports Betting Odds & Prop Resolution

List all sports PropLine currently polls. Returns sport keys (e.g. baseball_mlb, basketball_nba, soccer_epl) along with human titles and active status. Use this first to discover what sport_key values are valid for the other tools.

List upcoming events for a sport. Returns each event's id, home_team, away_team, commence_time. Use the returned event_id to drill into per-event odds, props, +EV, or results.

List the market types available for a specific event (e.g. h2h, spreads, totals, player_points, pitcher_strikeouts). Useful when you don't know which prop markets a given event carries.

Get live odds. If event_id is supplied, returns full per-event props for that event; otherwise returns bulk game-line odds for the whole sport. Pass markets as a comma-separated list (e.g. 'h2h,spreads,totals' or 'player_points,player_rebounds'). Response includes a bookmakers[] array across every book that carries the requested markets (currently up to 37 — sportsbooks: Bovada, DraftKings, FanD

Hobby+ endpoint. Returns the historical line-movement snapshot series for an event (every recorded price/point change per outcome over the event's lifetime). Free tier returns market structure with redacted snapshots and an upgrade pointer. Supports period-historical filters: from/to (absolute ISO), relative_from/relative_to (offsets to commence_time like '-3h' or '0'), interval downsample ('30s'/

Hobby+ endpoint. Returns the OPENING and CLOSING line per (book, market, outcome) for an event. Closing = the last snapshot at or before commence_time (price/point/closing_at); opening = the first snapshot PropLine holds for the outcome, however far before kickoff the book posted it (opening_price/opening_point/opening_at); pass opening_window to limit that lookback. Canonical CLV-tracking helper;

Hobby+ endpoint. Grades PLACED bets against their closing lines. Closing line value is the only durable proxy for whether a bettor has edge: did the price they took beat the number the market settled on? Send the bets and each comes back with its closing price, the de-vigged closing fair probability, CLV, and — once the game settles — the graded resolution and actual stat value, plus a portfol

Hobby+ endpoint. Prices a same-game parlay at the BOOK'S OWN correlated odds — the price a FanDuel customer would be offered for that exact slip right now, not a model of it. bookmaker is fanduel (default, its own pricer), draftkings (its SGP widget's pricer), betonlineag / lowvig (the Sportcast engine both share, same builder price), or 'all' to quote every book on the same legs in one call —

Backfill-pass / Enterprise only. Bulk line-movement tick history as CSV — every recorded odds snapshot (price + line, per book, including period markets) across a whole sport, one row per (outcome, snapshot). This is the raw firehose no subscription tier can bulk-pull (Pro/Streaming use propline_get_odds_history per event instead). REQUIRES a since/until window to keep the pull bounded — the f

Free-tier endpoint. Returns season-long futures (outright) markets for a sport — championship/Super Bowl/division/conference winners, MVP and award winners, season win totals — aggregated across Bovada, FanDuel, DraftKings, Pinnacle, and Kalshi. One row per (futures event, book, market) with each team/player outcome and its price. Marquee markets (Super Bowl winner, MVP, division/conference) a

Free-tier endpoint. Returns recent and live game scores plus status (scheduled, live, final) for a sport. Useful for: 'is this game over yet, what was the final score'.

Free-tier reference math. Returns the PrizePicks Power Play (all legs must hit) and Flex Play (partial payouts) entry payout schedule for 2-6 legs, plus the per-leg breakeven win probability for each play. Pass leg_win_prob (e.g. 0.58) to also get expected_return (per $1) and is_plus_ev per play — the slip-level breakeven. Useful for: 'what hit rate do I need to beat a 4-pick PrizePicks Power pl

Free-tier endpoint. Returns the synthetic daily MLB Grand Salami for a given UTC date — total runs scored across every MLB game on the slate plus each book's implied Grand Salami line (median of per-game primary totals across our MLB books incl. Pinnacle, Polymarket, Matchbook, Smarkets). No retail sportsbook quotes this as a single market. Useful for: 'what's the total run line for tonight's fu

Free-tier endpoint. Returns the synthetic daily NHL goals total (hockey's equivalent of the MLB Grand Salami) for a given US Eastern date — total goals scored across every NHL game on the slate (including OT/SO) plus each book's implied Daily Goals Total line (median of per-game primary totals across our NHL books). No retail sportsbook quotes this as a single market. Useful for: 'what's the tot

Free-tier endpoint. Returns the factual volume of player props PropLine has graded against real box scores over the last N days (aggregated counts only): total graded/settled, games, sports covered, plus per-sport and top-market breakdowns. Useful for: 'how much graded prop data does PropLine have, what's the coverage'. A coverage proof, never a profitability claim.

Free-tier endpoint. Id crosswalk for one sport: one object per event from 3 days ago to 30 days ahead with PropLine's event id, commence_time, teams (+ team keys/ids), espn_event_id, mlb_game_pk, merged_from_event_ids, and each sportsbook's own event id + link under books. Useful for: 'join PropLine events onto ESPN / the MLB Stats API / a sportsbook's own feed', 'what is DraftKings' id for this g

Free-tier endpoint. How well each sportsbook prices player props: each book's closing prop prices are de-vigged and scored (Brier) against the real result and against the other books on the same line. Per book: props scored, brier, consensus_brier, skill_bp (> 0 = closer to the result than the market average) with a 95% interval, verdict (beats_market / trails_market / in_line) and margin_pct (ave

Free-tier endpoint. A golfer's completed rounds, newest first, with strokes, score to par and hole counts (eagles, birdies, pars, bogeys, doubles), plus last-5/10/20 averages. Every player in the field, back to 2024; a round in progress is never included. Filter by tour (pga, dp_world, liv, lpga, korn_ferry, champions). Hole counts are null on DP World, LPGA and some LIV rounds. Useful for: 'Schef

Free-tier endpoint. Golf tournaments we hold round data for, newest first, with player and round counts. Filter by tour (pga, dp_world, liv, lpga, korn_ferry, champions) and season.

Book-agnostic raw box-score stats for an event. Returns per-player stats (e.g. strikeouts, hits, points, rebounds, shots-on-goal) decoupled from any sportsbook's lines. LIVE during games for major US sports (MLB + WNBA now; NFL, NCAAF, NBA, NHL at season start): while the event's status is in_progress, stats refresh ~every 90 seconds with cumulative in-game values — use this to answer 'how is th

Pro-tier endpoint. Returns graded prop outcomes for a completed event — every Over/Under marked won, lost, push, or void with the actual stat value next to the line. The single most distinctive feature vs the-odds-api: they don't grade props at any tier. Free tier returns the same structure with resolution and actual_value redacted plus an upgrade pointer.

Game context for an event — the conditions a prop settles under. MLB: probable starting pitchers and their throwing hand (L/R/S — platoon-split context for every batter prop), a confirmed-lineup flag, the home-plate umpire, and first-pitch weather (temperature, wind, precipitation) at outdoor / open-roof venues (indoor venues return weather=null). NFL & NCAAF: the venue and kickoff weather. Th

Line movement + steam detection from the snapshot tick history. Per (book, market, outcome): opening line, latest line, signed implied-probability shift, point shift, direction. The steam[] array flags outcomes that multiple books moved the same direction — the classic sharp-money signal, computed across all 37 books PropLine polls. When a book moves the line itself, that outcome's prob_shift is

Find a player by name fragment and get their stable player_id (e.g. 'mlb:677951') plus every spelling the books use (known_names). Free tier. Pass the player_id as player_name to propline_get_player_history / propline_get_player_trends to avoid name-spelling ambiguity.

Player prop history across recent games for one market. Returns each prior prop this player took with line, prices, resolution, actual value, is_main_line (the book's main line vs an alt-ladder rung) and line_moved_in_play. Pass main_line_only=true to drop alt rungs. Pro tier returns full data; free tier returns redacted resolution/actual_value with an upgrade pointer.

A player's recent games with every raw box-score stat per game — one call instead of one request per event. Use this to answer 'how has X actually performed lately?' and to build L5/L10/L20, season splits and head-to-head yourself. Pass `opponent` for H2H (accepts a full name, nickname or abbreviation — 'Boston Red Sox', 'Red Sox', 'BOS'); the limit applies AFTER that filter, so opponent + lim

Hit-rate trends / last-N-games over rate for a player — unique to PropLine's prop-resolution data. For each market the player has graded history in, returns over/under/push splits across the last 5/10/20/50 graded games, current streak, average actual stat, and the recent line. This is the 'did X go over in N of his last M games?' surface. Omit `market` for all markets, or pass one to scope (e.g

Pro-tier endpoint. Returns cross-book +EV per outcome for an event. We anchor on a sharp book, remove vig, derive a no-vig fair line, and compute EV% per book at the same line. Outcomes are sorted with +EV plays floated to the top of each line group. PrizePicks is excluded from EV math (DFS payouts aren't comparable to per-book prices). The anchor is chosen PER LINE in the order pinnacle → polym

Market-implied consensus projection per (market, player) for an event: the line where the no-vig P(over) crosses 50%, median across contributing sportsbooks. Use it to validate statistical or fantasy projections against the live market. These are MARKET-IMPLIED values derived purely from sportsbook prices — never a forecast, and no accuracy claim is made; present them as 'the market implies X',

Cross-book line shopping (Hobby+ for prices; free tier gets the full structure with book identities + best-first ranking but prices nulled and redacted:true). For every (market, player, line) tuple on an event, returns the single best American price across all comparable books, plus an all_prices array sorted best-first (one row per book, each with last_update). Companion to propline_get_event_ev:

List the API key's webhook subscriptions (Streaming Lite tier and up; other tiers get a 403 with an upgrade URL). Read-only: signing secrets are always masked, and this server deliberately has no create/update/delete tools — manage subscriptions via the REST API or SDKs. Each row shows url, subscribed events (line_movement, resolution, steam, market_suspended, ev), filters (incl. min_ev_pct / ma

Recent delivery attempts for one webhook (Streaming Lite tier and up), newest first — the debugging surface for 'why isn't my webhook firing'. Each row: status (pending/success/failed), HTTP response_code, attempts, delivered_at and the payload that was sent. A pending row with attempts > 0 is mid-retry-backoff; status 'failed' with response_code null means the endpoint was unreachable or timed

Re-read a webhook subscription's events in order from a cursor — answers 'my endpoint was down, what did I miss?'. Every delivery carries an X-PropLine-Sequence header, a counter monotonic WITHIN one subscription; pass the highest one the user processed as since_seq. Do NOT use the delivery id as the cursor: that id is global across all subscriptions, so gaps in it are other customers' traffic a

Create a free personal PropLine API key for the user and EMAIL it to them. Use this when the user wants their own key — e.g. they hit a shared-demo-key rate limit, a paid field came back redacted, or they ask how to get a key. Only call it with an email address the user explicitly gave you for this purpose in this conversation; never guess, reuse one from elsewhere, or sign up a third party. The
