What Betstamp API Is
Betstamp API gives your code odds from many sportsbooks (betting sites). An API is a way for your code to ask a service for data. Betstamp says it cleans up the odds from each book so they look the same. That way you can compare them without extra work.
It also sells a second API for prediction markets. Those are sites where people trade on whether events will happen. Examples named on its pages include Kalshi and Polymarket.
Who Betstamp API Is For
This is for builders who need broad odds data and are fine talking to a sales team. Think of a small company, a team building an odds screen, or a coder with a serious model. The pages show player props, live odds and past markets.
It is likely not for you if you want to sign up on your own and pay with a card. Access starts with a demo request. A casual hobbyist may find that too slow.
How It Works
- Request a demo. You ask for access. That is how you get an API key, which is a private code that proves who you are.
- Try a trial key. The pages say trial keys are available so you can check the data first.
- Send your key with each call. The docs say every call needs your key in a header.
- Pull or stream. REST means your code asks for data each time. SSE is a live stream that sends you changes. Betstamp offers both.
- Look up the basics. Extra calls list players, teams and games, so you can match the odds to the right event.
For prediction markets, you can get order books, top prices, volume and how much money sits in a market.
What to Weigh Before You Pay
No public prices. You talk to sales first.
Limits by plan. Betstamp says it limits how often you can ask, and it sets a monthly cap that depends on your plan. A busy app can hit those limits. Ask what yours would be.
Speed claims. Betstamp says its feeds are very fast. Those are its words. Use a trial key to check the speed for the sports you care about.
History. The pages mention past markets but do not say how far back they go. Ask before you build a model that needs years of data.
Bottom Line
Betstamp API suits teams and serious builders who want many books, props and prediction markets in one place. If you want a plan you can buy today, look elsewhere. Ask for a trial key first.
