BetMGM is registry-listed, but current bookmaker and market presence can vary. Check GET /v1/bookmakers, the live coverage page, and the event snapshot before making BetMGM a required production dependency.

How to use the BetMGM API

Verify current BetMGM coverage first, then request the event snapshot and preserve the response's freshness fields.

  1. Verify BetMGM availability

    Start with GET /v1/bookmakers and the live coverage catalog. Registry presence does not guarantee a current price for every event.

  2. Find a priced event

    Choose an event that lists betmgm in its available bookmaker coverage before requesting a snapshot.

  3. Request the BetMGM board

    Use bookmakers=betmgm and keep the normalized line, selection, price, and freshness fields intact.

  4. Handle coverage changes

    Treat the current snapshot as authoritative, and fall back to other selected US books when BetMGM is not present.

BetMGM API FAQs

Coverage-first answers about the BetMGM key, current availability, US market labels, American odds display, and affiliation.

Is this the official BetMGM API?

No. odds-api is an independent data service and is not affiliated with, endorsed by, or sponsored by BetMGM. It provides market data only and does not place bets or manage BetMGM accounts.

Is BetMGM available for every US event?

No. BetMGM can be registry-listed without appearing in every current event or recent coverage window. Confirm GET /v1/bookmakers, live coverage, and the event snapshot before depending on it.

What is the BetMGM bookmaker key?

Use betmgm in bookmaker filters when that key is available to your account and attached to the event. The snapshot query is bookmakers=betmgm.

How are BetMGM run lines and puck lines represented?

US-facing run line, puck line, and point spread labels map to the normalized handicap bet_type with a line value and side. Keep the sport context when presenting that field.

Does the BetMGM page promise a refresh speed?

No fixed event-level cadence is claimed here. The service publishes its adaptive pre-match refresh model separately, while current latency and availability measurements appear on the status page.
