It links a displayed opportunity to proposed trade legs and an investment amount; execution remains a separate action.

The scanner filters opportunities by platform and category, while the sizing calculator shows proposed legs for a chosen investment. Plan-dependent tools extend into sportsbook comparisons, funding rates, weather and market odds. The public demo is delayed, so it is useful for inspecting the interface rather than establishing an executable current price. The API returns identifiers, links, prices, gross and net profit figures and reasons some books were skipped. Before integrating, verify a real response: the endpoint overview and response reference use different opportunity structures. A matched pair still needs a check of both contracts’ settlement rules, fees and available depth. ### Who it is for - Traders researching equivalent outcomes across venues. - Developers needing opportunity data for a chosen investment size. - Researchers shortlisting spreads before checking order books. ## Features and coverage - **Cross-market scanner** Filter platforms and categories and sort displayed opportunities. - **Trade-leg sizing** Inspect proposed legs for a specified investment amount. - **Opportunity context** Read API identifiers, links, prices, gross/net profit and skipped-book reasons. - **Additional research tools** Plan-dependent scanners cover sports, weather, funding rates and market odds. - **Bearer-authenticated API** Request structured opportunity data with a dashboard API key. - **Delayed public demo** Inspect the interface before subscribing, keeping the demo delay in mind. ## Workflows with ArbBets ### Evaluate a displayed spread An execution plan needs more than the scanner's match.

Inspect the demo and choose the plan covering the tools you need. 2. For API use, create a dashboard key and use bearer authentication. 3. Set investment and min\_profit in dollars. 4.
