DraftKings Odds API

DraftKings is the book most US products are measured against, and its market tree is deeper than the headline lines suggest. The SportsGameOdds API delivers all of it as structured JSON — no scraping, no unofficial endpoints — in the same schema as every other book we carry.

Quick Start: Requesting DraftKings Odds

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

What a DraftKings price looks like

Every event returns an odds object keyed by oddID, with each book's price inside byBookmaker:

{
  "eventID": "...",
  "leagueID": "NFL",
  "odds": {
    "points-home-game-sp-home": {
      "oddID": "points-home-game-sp-home",
      "opposingOddID": "points-away-game-sp-away",
      "marketName": "Spread",
      "statID": "points",
      "statEntityID": "home",
      "periodID": "game",
      "betTypeID": "sp",
      "sideID": "home",
      "fairOdds": "-106",
      "fairSpread": "-3.5",
      "bookOdds": "-110",
      "bookSpread": "-3.5",
      "byBookmaker": {
        "draftkings": { "odds": "-110", "spread": "-3.5", "available": true },
        "fanduel": { "odds": "-115", "spread": "-3.5", "available": true },
        "pinnacle": { "odds": "-104", "spread": "-3", "available": true }
      }
    }
  }
}

Odds and lines come back as strings, which preserves the leading + on plus-money prices. fairOdds is the vig-free consensus across every book in the feed — a neutral benchmark to measure any single book against, including DraftKings.

Period markets go deeper than most feeds

This is where DraftKings coverage separates itself. Alongside full-game lines, the API carries period markets across 23 period codes:

• Baseball — inning by inning (1i through 9i), plus first three, first five and first seven innings (1ix3, 1ix5, 1ix7)
• Football and basketball — quarters (1q–4q) and halves (1h, 2h)
• Hockey — periods (1p, 2p, 3p)
• Soccer — regulation (reg) and halves

Swap the period segment of any oddID to move between them. A first-five-innings total is points-all-1ix5-ou-over; the full-game version is points-all-game-ou-over.

Coverage

DraftKings spans 23 leagues in the API: NFL, NCAAF and the CFL; NBA, WNBA and college basketball; MLB, plus Japan's NPB and Korea's KBO; NHL and Sweden's SHL; UFC; and soccer across the Premier League, La Liga, Bundesliga, Serie A, Ligue 1, Eredivisie, the Champions League, the Europa League, MLS, Liga MX and international fixtures.

Around 40 stat types are mapped, covering game lines, team totals and the player prop catalogue. For the current per-league breakdown of exactly which markets are supported, use the Supported Markets reference or the /markets endpoint — both are generated from live data rather than maintained by hand.
