The Problem
Prediction market data is a mess
Every platform has different APIs, formats, and quirks. Building reliable data infrastructure yourself takes months.
Fragmented
Every platform has different APIs, auth methods, and data formats.
Slow
Polling APIs isn't real-time. You're always behind the market.
Incomplete
Historical data is hard to find and even harder to trust.
Complex
Polymarket requires blockchain indexing expertise and reorg handling.

We handle the complexity. You get clean, real-time data through a single API.
