Caesars Odds API: Get Caesars Sportsbook Lines Into Your App

No. Caesars Sportsbook has no public odds API. Caesars Entertainment runs a developer portal at developer.caesars.com, but it sits behind a login, and nothing public says that it covers sportsbook odds or offers a key to outside developers. This page covers the sportsbook, not the hotel and rewards side of Caesars. With the portal closed, developers turn to a Caesars odds API run by a third party, which gathers Caesars prices and serves them next to other books. Those feeds are the subject of our sportsbook API guide.

FanDuel, DraftKings and BetMGM each license their odds to media companies. Caesars has no such deal that we could find today. ESPN, for one, takes its odds from DraftKings as its exclusive provider. We also found no Caesars affiliate page that offers an odds feed.

Caesars runs no prediction market either, so it has no exchange API. In October 2025 its CEO, Tom Reeg, said Caesars is staying out of prediction markets: "We will not put any of our licenses at risk."

1. An odds API that carries Caesars

For Caesars prices, start here. You get a key the same day, the provider deals with the Caesars app and its state paths, and Caesars comes back in the same schema as every other book, over REST or a push feed. One tip from our own data: some feeds still list Caesars under its old William Hill US name, so search a provider's book list for both names. If you want to start free, our free odds API guide shows what several feeds include on their free plans.

2. A licensed feed

Broadcasters and operators can license enterprise feeds from the official data partners of the leagues. That path runs through sales calls and legal review to a negotiated price. We found no feed that Caesars sells itself, so for Caesars prices an odds API stays the practical route.

3. Scraping

Scraping Caesars is a bad idea. Buy the feed. The betting app is a JavaScript app with a separate path for each state, so the odds sit behind a state choice, and the main caesars.com site runs Imperva web protection. The Caesars terms say the service is "for Your personal, entertainment use" and bar any commercial purpose. They also ban copying or exploiting "any portion of the Platforms" for commercial gain, and the Unfair Advantage Policy forbids "the use of BOTs, AI". A scraper behind a commercial product breaks those terms and puts the account at risk.

The next table holds every odds API in our directory that carries Caesars, with a source and a date on each row.

Read each row by its source. Where our probe verified Caesars prices, the row shows the leagues and market families we saw, from moneylines, spreads and totals in the NFL, NBA, MLB and NHL to college football, soccer and more. Where the source is the provider's docs, the row confirms that Caesars is in its book list, though not which leagues it covers.

Player props and live odds are part of the Caesars menu, and its NFL page advertises "live odds, player props, & more". Verified providers showed Caesars player props in our probe. For prop structure, see the player props API guide, and for in-play delivery, our live sports odds API guide.

Parlays go big at Caesars. Its Super Parlay lets a customer combine several same-game parlays with other parlays and straight bets on one ticket. Ask a provider whether it carries same-game parlay prices before you build a feature on them.

NFL data has an official source behind it. In September 2021 Caesars became the second US operator to sign up for the NFL's official data feed, as one of its three exclusive partners. Caesars shows American odds by default, and its Odds Settings menu switches to decimal or fractional.

Caesars runs its own platform. When Caesars bought William Hill, it took over Liberty, the William Hill US platform, and in August 2021 it relaunched Caesars Sportsbook on it. Books on different platforms post different numbers, so a Caesars line gives your users one more price to compare against FanDuel, DraftKings and BetMGM.

The footprint is wide. After its Missouri launch in December 2025, Caesars counted 34 states and jurisdictions, 29 of them with mobile betting. A user in any of those mobile markets can bet the Caesars line you show, and the app has carried Caesars Rewards since the 2021 relaunch.

The William Hill history also explains a data quirk. In states that required in-person sign-up, such as Nevada, Illinois and Washington, D.C., the app launched as "Caesars Sportsbook by William Hill", and Caesars' terms page still links a William Hill Nevada site. If a feed shows a William Hill US book, read it as Caesars before you count it twice.

Line shopping. Add Caesars to a screen with FanDuel, DraftKings and BetMGM, and a user can find the best price of the four at once. The Coverage Map for Caesars lists the feeds that pair Caesars with each other book you name.

Arbitrage and value against sharp books. Benchmark Caesars against a sharp market such as Circa. If the Caesars price beats the fair price implied by the sharp book, the bet carries positive expected value. A wide enough gap between two books lets a bettor back both sides and lock in a profit.

Parlay and props tools. Super Parlay tickets mix same-game parlays with other bets, so a parlay calculator that prices Caesars legs fits how its customers bet. In a prop screener, set Caesars props next to the other US books to flag lines that sit apart.

Closing line value. Save the last Caesars price before each game starts and set it against the price each user took. A user who beats that number week after week is finding value, whatever the short-run results say. Our historical odds guide shows how much history each type of feed stores, which sets how far back that comparison can run.

Caesars takes every bet in its own app, and your app only shows odds that a provider licenses to you. Check three things before launch.

Read your provider's terms on display, because some plans cover internal use only and a public app needs a plan that allows redistribution. Mind the map: Caesars takes mobile bets only in its mobile markets, and its state picker mixes mobile, retail and casino locations, so check a user's state before you show a "bet at Caesars" button. Watch the owner. In May 2026 Fertitta Entertainment agreed to buy Caesars Entertainment for about $17.6 billion, subject to shareholder and regulatory approval. Keep the book id in your config so a brand change costs you one edit. This is not legal advice.
