Build an Odds Comparison App in Minutes
One API call. 40+ sportsbooks. Normalized data. Build a production-ready odds comparison tool without scraping or data pipelines.
The fastest way to build an odds comparison app is with SharpAPI. SharpAPI returns normalized odds from DraftKings, FanDuel, BetMGM, Caesars, Pinnacle, Bet365, and more sportsbooks in a single API call. Every book uses the same schema, consistent field names, market types, and team identifiers, so you skip months of scraping and normalization work. The free tier gives you 12 requests/minute to prototype. Add SSE streaming as a $99/mo add-on for push updates, delivered from our edge in roughly 1-3 seconds.
Why Developers Choose SharpAPI for Odds Comparison
Normalized Data
Every sportsbook mapped to one consistent schema. Same field names, same market types, same team IDs. Write one parser, support every book.
Real-Time Updates
SSE streaming pushes each odds change to your app as soon as we capture it, roughly 1-3 seconds from our edge to your client.
40+ Sportsbooks
DraftKings, FanDuel, BetMGM, Caesars, Pinnacle, Bet365, and more. Each plan selects how many of them you get — 5 on Hobby, 25 on Sharp — and the free tier covers DraftKings and FanDuel.
How It Works
1. Fetch Odds
Call the REST endpoint with a sport and market type. One response contains odds from every sportsbook for every matching event.
2. Display in a Table
Render the normalized data in a comparison table. Every sportsbook uses the same field names, so your UI code stays simple.
3. Stream Updates via SSE
Connect to the SSE endpoint to receive push-based updates. When any odds change at any sportsbook, your table updates as soon as we capture the new price.
Code Example: Odds Comparison Table
Fetch Odds from All Books
import { SharpAPI } from '@sharp-api/client';
const sharp = new SharpAPI('sk_live_your_key');
// Fetch moneyline odds for all NBA games
const odds = await sharp.odds.get({
league: 'NBA',
market: 'moneyline'
});
// Each event contains odds from every book
odds.data.forEach(event => {
console.log(event.name);
event.odds.forEach(line => {
console.log(
` ${line.sportsbook}: ${line.selection}`
+ ` ${line.odds_american}`
);
});
});Stream Real-Time Updates
// Real-time odds updates via SSE
const url = 'https://api.sharpapi.io'
+ '/api/v1/stream'
+ '?channel=odds&league=NBA'
+ '&api_key=sk_live_your_key';
const es = new EventSource(url);
es.addEventListener('odds:update', (e) => {
const data = JSON.parse(e.data);
// Update your comparison table row
updateRow({
event: data.event,
sportsbook: data.sportsbook,
selection: data.selection,
odds: data.odds_american,
previousOdds: data.previous_odds,
});

Frequently Asked Questions
How do I build an odds comparison website?
You need a real-time odds API that covers multiple sportsbooks in a normalized format. SharpAPI returns odds from 40+ sportsbooks in one API call with consistent field names, so you can render a comparison table immediately without building data pipelines or scrapers. Sign up for a free API key, call the odds endpoint for your sport, and display the results.
Can I get odds from multiple sportsbooks in one API call?
Yes. SharpAPI returns odds from all covered sportsbooks (DraftKings, FanDuel, BetMGM, Caesars, Pinnacle, Bet365, and more) in a single API response, grouped by event and market. No need to make separate calls per book.
Do I need to normalize odds data myself?
No. SharpAPI normalizes all odds into a consistent schema before delivering them. Every sportsbook uses the same field names, market types, and team identifiers, so you write one parser and it works for every book.
How do I keep odds updated in real-time?
SharpAPI offers Server-Sent Events (SSE) streaming as a $99/mo add-on on any paid plan. Connect once to the stream endpoint and receive push-based updates whenever odds change, with no polling. Delivery from our edge takes roughly 1-3 seconds; end-to-end freshness, which also includes how often each sportsbook can be captured, is 10-30 seconds for major books.
What does the free tier include for odds comparison?
The free tier includes 2 sportsbooks (DraftKings and FanDuel) and all sports at 12 requests per minute via REST. It is ideal for prototyping your odds comparison app. Upgrade to $79/month for undelayed data, more sportsbooks, and higher rate limits, then attach SSE streaming as a $99/mo add-on.
