BetMGM Odds API
BetMGM doesn't offer a public API. SharpAPI gives you normalized BetMGM odds alongside the other books we carry, 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 the other books we carry. 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 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. Push-based delivery removes your poll interval. End-to-end freshness also depends on how often each sportsbook can be captured.

Frequently Asked Questions
Does BetMGM have a public odds API?
No. BetMGM does not offer a public developer API for odds data. Their internal API is undocumented, changes frequently, and is not intended for third-party use. Scraping it violates their terms of service. SharpAPI provides normalized BetMGM odds through a stable, documented API.
How does SharpAPI get BetMGM odds?
SharpAPI collects BetMGM odds through proprietary adapters that normalize the data into a consistent schema alongside the other books we carry. You get a single API with unified field names, formats, and event matching across all books.
Can I compare BetMGM odds to other sportsbooks in one API call?
Yes. SharpAPI returns odds from all sportsbooks in a single response, making it easy to compare BetMGM lines against the other books we carry including DraftKings, FanDuel, Pinnacle without managing multiple data sources.
What markets does SharpAPI cover for BetMGM?
SharpAPI covers the major markets for BetMGM including moneylines, spreads, and totals across NFL, NBA, MLB, NHL, NCAAF, NCAAB and WNBA, plus tennis, soccer and table tennis. Player prop coverage is expanding. Check the docs for current market availability.
How fast are BetMGM odds updates on SharpAPI?
Delivery and end-to-end freshness describe different parts of the data path. Delivery of BetMGM line changes from our edge to your client is push-based over SSE streaming (a paid add-on on top of any paid plan). End-to-end freshness also depends on how often the source can be captured. Capture cadence, not transport, sets how fresh a line is.
