Build a Pre-Game Sports Betting Arbitrage Scanner

## Project Overview I am looking for an experienced developer to build a real-time pre-game sports betting arbitrage scanner. The objective is to identify arbitrage opportunities where **one side of every arbitrage must be on Roobet**, and the other side is on another sportsbook or prediction market. This project is **pre-game only**. Live/in-play betting is not required. ## Sportsbooks to Compare Roobet must be compared against: * Pinnacle * Bookmaker * BetOnline * Polymarket * DraftKings * FanDuel * Caesars Sportsbook * Betrivers I am open to adding additional sportsbooks if they can be integrated easily. ## Markets Required The scanner should support the following **pre-game** markets: * Moneyline * Main Point Spread * Main Game Total (Over/Under) * Alternate Point Spreads * Alternate Game Totals (Over/Under) Player props, same-game parlays, and live betting are **not** required. ## Requirements The application should: * Pull pre-game odds using official APIs where available or reliable third-party APIs. * Match the same event across sportsbooks. * Correctly compare main and alternate lines. * Detect arbitrage opportunities in real time. * Calculate: * Arbitrage percentage * Recommended stake sizing on both sides * Guaranteed profit * Display: * Event * Market * Line (e.g. -7.5, +3.5, O/U 221.5) * Sportsbooks * Odds * Profit % * Refresh odds automatically throughout the day with the lowest practical latency. ## Nice-to-Have Features * Filter by sport or league * Filter by sportsbook * Minimum arbitrage percentage filter * notifications when plays become avaliable * Historical log of detected opportunities * Clean documentation ## Preferred Tech Stack I'm open to recommendations ## Deliverables * Complete source code * Installation guide * Documentation * Configuration instructions for API keys * Ability to run locally or on a VPS ## When Applying Please include: 1. Your experience building sports betting or odds comparison software. 2. Which APIs you recommend for each sportsbook. 3. Your proposed architecture for matching events and markets across sportsbooks. 4. Estimated timeline. The primary goal is a fast, reliable scanner that continuously identifies **pre-game arbitrage opportunities**, with **Roobet always being one side of every arbitrage** and the other side coming from one of the supported sportsbooks or prediction markets.
