Sportsbook API

Caesars Odds API

Caesars Sportsbook doesn't offer a public API. SharpAPI gives you normalized Caesars odds alongside 39+ other sportsbooks, with +EV detection and real-time streaming.

ByMike·Founder, SharpAPI

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 39+ other sportsbooks. 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. No polling, no missed line movements. Delivery from our edge is roughly 1-3 seconds, end-to-end freshness 10-30 seconds for major books.

Get Caesars Odds in Code

REST: Query Caesars Odds

import { SharpAPI } from '@sharp-api/client';

const sharp = new SharpAPI('sk_live_your_key');

// Get NBA odds from all books
const odds = await sharp.odds.get({
  league: 'NBA',
  sportsbook: 'caesars'
});

odds.data.forEach(event => {
  console.log(event.event_name);
  console.log(event.odds_american);
  console.log(`EV: ${event.ev_percent}%`);
});

SSE: Stream Caesars Updates

// Real-time Caesars odds via SSE
const url = 'https://api.sharpapi.io'
  + '/api/v1/stream'
  + '?channel=odds&league=NBA'
  + '&sportsbook=caesars'
  + '&api_key=sk_live_your_key';

const es = new EventSource(url);

es.addEventListener('odds:update', (e) => {
  const data = JSON.parse(e.data);
  // Fires when Caesars
  // lines move
  console.log(data.event_name);
  console.log(data.odds_american);
});

How fast are Caesars odds updates on SharpAPI?

Two numbers, and they measure different things. Delivery of Caesars line changes from our edge to your client is roughly 1-3 seconds over SSE streaming (a paid add-on on top of any paid plan).
