Could you build this?

Partial Serving an API with CSV/JSON and generating client SDKs is trivial, but building accurate predictive models, power rankings, and win probabilities across 12 sports requires substantial quantitative sports modeling and live data licensing.

What it would actually take: A functional system requires integrating real-time and historical sports data feeds (e.g., Sportradar, Opta), storing game-by-game statistics in time-series databases, and running specialized statistical models (Glicko-2, Elo, Bradley-Terry, or Poisson regression variants) calibrated to betting lines. Automated pipelines would scrape or ingest final scores, evaluate model calibration/Brier scores, and publish public grade sheets. The barrier is acquiring consistent sports data and creating mathematically viable prediction models.
