FanDuel Odds API

FanDuel is one of the two books almost every US-facing product has to show, and its prop catalogue is among the deepest in the market. The SportsGameOdds API delivers it as structured JSON — no scraping, no unofficial endpoints — in the same schema as every other book we carry.

Quick Start: Requesting FanDuel Odds

FanDuel odds arrive inside the standard events response. Filter with bookmakerID:

What a FanDuel price looks like

Every event returns an odds object keyed by oddID, with each book's price inside byBookmaker. Here's a player points prop:

{
  "eventID": "...",
  "leagueID": "NBA",
  "odds": {
    "points-ANTHONY_EDWARDS_1_NBA-game-ou-over": {
      "oddID": "points-ANTHONY_EDWARDS_1_NBA-game-ou-over",
      "opposingOddID": "points-ANTHONY_EDWARDS_1_NBA-game-ou-under",
      "marketName": "Anthony Edwards Points Over/Under",
      "statID": "points",
      "statEntityID": "ANTHONY_EDWARDS_1_NBA",
      "playerID": "ANTHONY_EDWARDS_1_NBA",
      "periodID": "game",
      "betTypeID": "ou",
      "sideID": "over",
      "fairOdds": "-108",
      "fairOverUnder": "26.5",
      "bookOdds": "-112",
      "bookOverUnder": "26.5",
      "byBookmaker": {
        "fanduel": { "odds": "-105", "overUnder": "27.5", "available": true },
        "draftkings": { "odds": "-115", "overUnder": "26.5", "available": true }
      }
    }
  }
}

Note that each book carries its own overUnder, not just its own price — FanDuel is a point higher than DraftKings above. Comparing prices without comparing lines is the most common mistake when building a consensus, so read both fields together. Odds and lines are strings, which preserves the leading + on plus-money prices.

Coverage

FanDuel spans 26 leagues in the API — the broadest of the major US books on individual sports:

• Football — NFL, college football, CFL
• Basketball — NBA, WNBA, college basketball
• Baseball — MLB, plus Japan's NPB and Korea's KBO
• Hockey — NHL, Sweden's SHL
• Soccer — Premier League, La Liga, Bundesliga, Serie A, Ligue 1, Eredivisie, Champions League, Europa League, MLS, Liga MX, international fixtures
• Individual sports — UFC, PGA Tour golf, ATP and WTA tennis

Around 33 stat types are mapped across roughly 250 distinct market definitions, and period markets run to 23 codes — inning-by-inning baseball, quarters, halves and hockey periods. Swap the period segment of any oddID to move between them.

For the current per-league breakdown, use the Supported Markets reference or the /markets endpoint — both are generated from live data rather than maintained by hand.
