ESPN BET Odds API

ESPN BET reaches an audience that arrives through ESPN rather than through a betting app, which makes it a useful book to show in any consumer-facing product. The SportsGameOdds API delivers its odds as structured JSON — no scraping, no unofficial endpoints — in the same schema as every other book we carry.

Quick Start: Requesting ESPN BET Odds

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

What an ESPN BET price looks like

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

{
  "eventID": "...",
  "leagueID": "NBA",
  "odds": {
    "points-away-game-sp-away": {
      "oddID": "points-away-game-sp-away",
      "opposingOddID": "points-home-game-sp-home",
      "marketName": "Spread",
      "statID": "points",
      "statEntityID": "away",
      "periodID": "game",
      "betTypeID": "sp",
      "sideID": "away",
      "fairOdds": "-105",
      "fairSpread": "+4.5",
      "bookOdds": "-110",
      "bookSpread": "+4.5",
      "byBookmaker": {
        "espnbet": { "odds": "-108", "spread": "+4.5", "available": true },
        "draftkings": { "odds": "-110", "spread": "+4.5", "available": true },
        "fanduel": { "odds": "-112", "spread": "+4", "available": true }
      }
    }
  }
}

Spread markets carry their line in fairSpread / bookSpread, and per book in spread — not in the overUnder fields that totals use. Values are strings, which is what keeps the leading + on the away side's handicap intact.

Coverage

ESPN BET carries the markets you would expect from a major US book: moneylines, spreads and totals, team totals, alternate lines, player props across the main US sports, and half and quarter markets.

Coverage varies by league and shifts as markets open and close, so rather than publish a list that goes stale, the authoritative source is live: the Supported Markets reference and the /markets endpoint both return the current per-league, per-bookmaker breakdown, generated from the same data that powers the API.

Use Cases

Sportsbook & Fantasy Apps — Recognisable branding matters in consumer products where users pick a book by name.

Arbitrage & +EV Tools — Measure ESPN BET against the vig-free fairOdds consensus rather than any single rival book. See also positive EV betting.
