What PredictionData.io data does SportsStack support?

We normalize real-time and historical odds from 200+ sportsbooks, player props, alternate lines, and prediction market data from Polymarket and Kalshi endpoints. Everything comes through SportsStack's unified API with Universal IDs for cross-referencing with stats, scores, and other providers.

How often is data synced?

PredictionData.io provides real-time streaming via Server-Sent Events and REST endpoints. SportsStack ingests and normalizes this data in near-real-time alongside all your other providers.

Can I use PredictionData.io alongside other odds providers?

Yes. SportsStack is built for multi-provider use. Combine PredictionData.io odds with Optic Odds, The Odds API, or OddsBlaze — all normalized into the same schema with Universal IDs.

Do I need a direct contract with PredictionData.io?

Yes — PredictionData.io requires a direct agreement (bring your own key). SportsStack handles the normalization, ID mapping, and schema unification so you can combine their data with other providers through one integration.

What makes PredictionData.io different from other odds providers?

PredictionData.io covers 200+ sportsbooks — significantly more than most odds providers — and includes prediction market data from Polymarket and Kalshi alongside traditional sportsbook odds. Their SGP Pricing Engine also provides same-game parlay pricing.
