What SportsGameOdds Is
SportsGameOdds is an odds API for developers. An API is a way for your code to ask a service for data. It covers odds, scores and settlement data. Settlement data tells you how a bet turned out.
It covers many sports and leagues, hundreds of player prop types, live odds and some past odds. It also lists prediction markets such as Kalshi and Polymarket.
Who SportsGameOdds Is For
This is for developers adding odds and scores to an app or model. It works for a hobby coder who wants a free plan to test ideas. It also works for a small business that needs more volume later.
The free plan is made for testing. It is not for you if you need fast updates on a tight budget, or if you want to resell data. The terms ban reselling.
How It Works
- Sign up. It is self-serve. You try it free. The homepage says a card is needed at sign up.
- Get a key. A key is a private code that proves who you are.
- Use the docs and tools. There are official libraries for JavaScript, TypeScript and Python. There is also an MCP server, which helps AI coding tools write correct code for the API.
- Ask for data. REST means your code asks for data each time. Odds, scores and results come back.
- Stream, on top plans. A WebSocket is a live stream that sends changes to you. The pricing page ties that to a custom plan, not the public ones.
What to Weigh Before You Pay
Free plan limits. The free plan updates slowly and covers fewer books and leagues. It is for testing. Check the table above for current limits.
Speed by plan. The company says odds update about every half minute to a minute on average. That is its claim. Live streaming is held for a custom plan.
Usage caps. Plans cap how often you can ask and how much data you get. A busy app can hit them.
History varies. Past odds depend on the league and your plan.
Refunds. Payments are not refunded, unless the law says so. A cancel takes effect at the end of the current term.
Extra tools. There are libraries and an AI helper, which can save time. They do not change the plan limits, so read those first.
Affiliates. The site links to an affiliate program. We could not read its terms, so we say nothing about it here.
No reselling. You can't sell or pass along the data.
Bottom Line
SportsGameOdds is a good fit for developers who want to start free and grow. Read the plan limits before you build on it. If you need a live stream on day one, plan on a custom deal.
