The product also covers sportsbook differences, funding rates, weather tools and developer data, with access split across plans.

Who it is for

Getting started

Before you start: The demo is delayed rather than a live execution feed.

  1. Inspect the demo and choose the plan covering your required tool.
  2. For API access, create a dashboard key and use bearer authentication.
  3. Set the investment and min_profit values in dollars.
  4. Inspect a current response before building a parser or execution workflow.

Useful links

What to check

  • The demo is delayed rather than a live execution feed.
  • The endpoint overview and response reference use different opportunity structures; verify the actual response schema.
  • A quoted spread depends on both contracts’ rules, available size and actual fills.
  • Data access does not submit both venue orders for you.

Our take on ArbBets

The scanner connects price differences with sizing tools and a documented paid API. Delayed demos and inconsistent response examples limit how much an integration can be assessed before purchase.
