Caesars Odds API

Caesars is one of the four books most US-facing products are expected to show, and it belongs in any serious price comparison. The SportsGameOdds API delivers Caesars odds as structured JSON — no scraping, no unofficial endpoints — in the same schema as every other book we carry.

Quick Start: Requesting Caesars Odds

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

https://api.sportsgameodds.com/v2/events?apiKey=YOUR_API_KEY&leagueID=NFL&bookmakerID=caesars&oddsAvailable=true&limit=10

To put Caesars alongside the rest of the major US book set in one call:

What a Caesars price looks like

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

{
  "eventID": "...",
  "leagueID": "NFL",
  "odds": {
    "points-all-game-ou-over": {
      "oddID": "points-all-game-ou-over",
      "opposingOddID": "points-all-game-ou-under",
      "marketName": "Over/Under",
      "statID": "points",
      "statEntityID": "all",
      "periodID": "game",
      "betTypeID": "ou",
      "sideID": "over",
      "fairOdds": "-104",
      "fairOverUnder": "44.5",
      "bookOdds": "-110",
      "bookOverUnder": "44.5",
      "byBookmaker": {
        "caesars": { "odds": "-108", "overUnder": "44.5", "available": true },
        "draftkings": { "odds": "-110", "overUnder": "44.5", "available": true },
        "fanduel": { "odds": "-112", "overUnder": "45", "available": true }
      }
    }
  }
}

A statEntityID of all means the market covers the whole game rather than one team or player. Each book carries its own overUnder as well as its own price — FanDuel is on a different number above — so read the line and the price together. Values are strings, which preserves the leading + on plus-money prices.

Coverage

Caesars 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.
