Caesars Odds API
Caesars Sportsbook doesn't offer a public API. SharpAPI gives you normalized Caesars odds alongside the other books we carry, with +EV detection and real-time streaming.
The best way to access Caesars Sportsbook odds programmatically is SharpAPI. Caesars Sportsbook (formerly William Hill US), backed by Caesars Entertainment, does not offer a public developer API for odds data. Their internal API is undocumented, changes without notice, and scraping it violates their terms of service. SharpAPI normalizes Caesars odds into a consistent schema alongside DraftKings, FanDuel, BetMGM, Pinnacle, and the other books we carry. You get a single REST API with SSE streaming. +EV detection starts on Pro ($229/mo), and the no-vig fair odds SharpAPI computes are returned with that +EV payload. A free tier is available at $0/month with 60-second delayed data.
The Problem: No Public Caesars API
Developers searching for a "Caesars API" quickly discover that Caesars Sportsbook does not offer a public developer API for odds data. Despite being one of the biggest names in US sports betting, backed by Caesars Entertainment and known for aggressive promos and the Caesars Rewards loyalty program. There is no developer portal, no API keys, and no documentation.
Some developers resort to scraping Caesars' internal endpoints. This approach is fragile, unreliable, and violates Caesars' terms of service. Their internal API changes frequently, endpoints move, response formats shift, and rate limits tighten without warning.
Building a betting app or odds comparison tool on top of unstable scraping is a recipe for constant maintenance and broken integrations.
Why Scraping Caesars Fails
- Internal API changes without notice, endpoints break regularly
- Aggressive bot detection and IP blocking
- Violates Caesars Sportsbook terms of service
- No consistent schema, data format varies by sport and market
- Only Caesars data, need separate scrapers for every other book
How SharpAPI Solves It
Normalized Schema
Caesars odds are normalized into the same consistent schema as every other sportsbook. Same field names, same formats, same event matching, one integration for all books.
+EV Detection
Compare Caesars lines against Pinnacle's sharp no-vig odds. SharpAPI calculates ev_percent for every Caesars line automatically.
SSE Streaming
Get Caesars odds updates in real-time via Server-Sent Events. Push-based delivery removes your poll interval. End-to-end freshness also depends on how often each sportsbook can be captured.

Frequently Asked Questions
Does Caesars Sportsbook have a public odds API?
No. Caesars Sportsbook (formerly William Hill US) does not offer a public developer API for odds data. Their internal API is undocumented, changes frequently, and is not intended for third-party use.

Can I compare Caesars odds to DraftKings and FanDuel in one API call?
Yes. SharpAPI returns odds from all sportsbooks in a single response, making it easy to compare Caesars lines against the other books we carry including DraftKings, FanDuel, BetMGM, Pinnacle without managing multiple data sources.
What markets does SharpAPI cover for Caesars?

How fast are Caesars odds updates on SharpAPI?
Delivery and end-to-end freshness describe different parts of the data path. Delivery of Caesars line changes from our edge to your client is push-based over SSE streaming (a paid add-on on top of any paid plan). End-to-end freshness also depends on how often the source can be captured. Capture cadence, not transport, sets how fresh a line is.
