How It Works

The scanner uses the-odds-api.com (free tier) to fetch live odds from DraftKings, FanDuel, BetMGM, Caesars, and more. For each game, it compares prices across bookmakers to find arbitrage — situations where the combined implied probability of all outcomes is less than 100%.

Example

Outcome	Bookmaker	Odds	Stake ($100 total)
Lakers Win	DraftKings	-110	$52.38
Celtics Win	FanDuel	+105	$47.62

Implied probability: 52.4% + 47.6% = 99.5% → 0.5% guaranteed profit 🏹

Input

Field	Type	Default	Description
`api_key`	string	—	Your API key from the-odds-api.com (free: 500 req/mo)
`sports`	array	NBA, MLB	Sports to scan for arbitrage
`regions`	string	`us`	`us`, `uk`, `au`, or `eu`
`min_arbitrage_pct`	number	0.5%	Minimum arb % to report (0.1–10%)

Output

Per-run JSON with:

Total opportunities — count of arb chances found
Top opportunities — up to 50 best arb plays sorted by % profit
Per-opportunity details — outcome names, bookmakers, odds (American), decimal odds, implied probabilities, stake split for $100 total, guaranteed profit
