5 Things We Didn't Expect While Building a Real-Time Sports Odds API
Short summary
Building a real-time sports odds API revealed that data normalization, monitoring, and infrastructure matter more than scraping. The engineers encountered challenges matching events across bookmakers, handling thousands of updates per second, and maintaining 24/7 reliability. Their learnings became PulseScore, which aggregates multiple bookmakers into a consistent developer-friendly API.
- •Data normalization and monitoring are bigger engineering challenges than scraping
- •Real-time systems require architecture for detecting changes within seconds with 24/7 uptime
- •Developers value consistent APIs over raw data; consistency becomes the core product
Generated with AI, which can make mistakes.
