betting-odds-tracker

Track where the smart money is going.

A real-time odds monitoring tool that tracks line movements across sportsbooks, identifies sharp money signals, and helps you find the best available odds for NBA, MLB, and Soccer.

The Problem

Odds are scattered across dozens of sportsbooks. Lines move fast. By the time you manually compare FanDuel, DraftKings, and BetMGM, the value is gone. And you have no idea whether that line move was driven by public money or sharps.

The Solution

betting-odds-tracker pulls odds from multiple sportsbooks through The Odds API, tracks every movement over time, and alerts you to sharp money signals -- all correlated with live game scores so you have full context.

What You Get

• Cross-book comparison: See moneyline, spread, and totals from every major sportsbook side by side
• Line movement tracking: Opening vs current line with timestamped snapshots
• Sharp money detection: Reverse line movement flags (when lines move against public betting percentages)
• Best available odds: Instantly see which book has the best price
• Live game context: Current scores pulled alongside odds for in-game correlation

Who This Is For

• Sports bettors who want to find the best line before placing a wager
• Sharp bettors who track line movement as an information signal
• Casual bettors who want to stop leaving money on the table by always betting at the worst number
• Analysts studying market efficiency in sports betting

API Usage & Rate Limits

The free tier of The Odds API allows 500 requests per month. The tracker is designed to be efficient with your quota:

Action	API Calls	Recommended Frequency
All NBA odds (3 markets)	1	Every 2-4 hours
All MLB odds (3 markets)	1	Every 2-4 hours
All Soccer odds (1 league)	1	Every 2-4 hours
Score settlement check	1	After games end

With 3 sports checked 4x/day, you use roughly 360 requests/month, leaving headroom for ad-hoc checks.

The tracker also caches responses locally (15-minute TTL) to avoid duplicate API calls within short windows.
