The Difference

Why unified data matters for builders

Other aggregator APIs

One API, but you still need to handle different response formats per platform.

// Different schema for each platform
polymarketData.outcomes[0].price
kalshiData.yes_price

// You still write mapping code
function normalizePrice(data, platform) {
  switch(platform) { ... }
}

Probalytics

One API, one schema. Same response format regardless of source platform.

// Same schema for ALL platforms
event.platforms.polymarket.price  // 0.52
event.platforms.kalshi.price      // 0.48

// No normalization code needed!
// Events already matched across platforms

// Same schema regardless of source!
console.log(event.platforms)
// { polymarket: { price: 0.52, volume: 1200000 },
//   kalshi: { price: 0.48, volume: 800000 } }

// No parsing, no mapping, no normalization code
