BetMGM Odds API
BetMGM doesn't offer a public API. SharpAPI gives you normalized BetMGM odds alongside 20+ sportsbooks — with +EV detection and real-time streaming.
The best way to access BetMGM odds programmatically is SharpAPI. BetMGM — the #3 US sportsbook backed by MGM Resorts and Entain — 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 BetMGM odds into a consistent schema alongside DraftKings, FanDuel, Pinnacle, and 17+ other sportsbooks. You get a single REST API with +EV detection, no-vig fair odds, and SSE streaming — starting at $0/month with a free tier.
The Problem: No Public BetMGM API
Developers searching for a "BetMGM API" quickly discover that BetMGM does not offer a public developer API for odds data. Despite being the #3 US sportsbook backed by MGM Resorts and Entain, there is no developer portal, no API keys, and no documentation.
Some developers resort to scraping BetMGM's internal endpoints. This approach is fragile, unreliable, and violates BetMGM's terms of service. Their internal API changes frequently — endpoints move, response formats shift, and rate limits tighten without warning.
BetMGM is known for wide market variety and competitive promos across most legal US states, making their odds data valuable. But building a betting app on top of unstable scraping is a recipe for constant maintenance and broken integrations.
Why Scraping BetMGM Fails
- Internal API changes without notice — endpoints break regularly
- Aggressive bot detection and IP blocking
- Violates BetMGM terms of service
- No consistent schema — data format varies by sport and market
- Only BetMGM data — need separate scrapers for every other book
How SharpAPI Solves It
Normalized Schema
BetMGM 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 BetMGM lines against Pinnacle's sharp no-vig odds. SharpAPI calculates ev_percent for every BetMGM line automatically.
SSE Streaming
Get BetMGM odds updates in real-time via Server-Sent Events. No polling, no missed line movements — instant delivery as odds change.
