What is a betting odds API?

A betting odds API gives developers programmatic access to real-time betting lines from sportsbooks. Instead of manually scraping websites or paying for expensive data feeds, you make simple HTTP requests and get structured JSON with current odds, lines, and player props.

PropLine's API covers moneylines, spreads, totals, and 60+ player prop markets. It's designed for developers building betting tools, analytics dashboards, line shopping apps, and prop betting models.

What you get

Game Lines

Moneylines, point spreads, and totals (over/under) for all 38 sports. Updated every 60 seconds (30s for in-progress games).

Player Props

60+ markets: pitcher strikeouts, player points, rebounds, assists, goalscorer props, fight props, and more.

Prop Resolution

Know if the bet won. We cross-reference actual stats to mark every prop as won, lost, or push.

Historical Odds

Track line movement over time. See how odds shifted from open to close.

Game Scores

Final scores and game status for all events. Free with every plan.

Python + Node SDKs
