Not all prediction market #APIs give you the same picture. Some show the latest probabilities... Others give you historical trades, order books, liquidity, and resolution data. And when you're building across Polymarket, Kalshi, and other platforms, those differences matter. We compared 5 prediction market APIs to see where they stand on: → Market coverage → Historical data → Real-time access → Resolution tracking Which one fits your project?

Not all exchange rates are created equal... The European Central Bank provides free... official exchange rates. ... but there's a catch: they update only once per working day. That's fine for accounting. Not necessarily for applications that depend on changing market conditions. So when should you use ECB rates, and when do market-based rates make more sense? In our latest FinFeedAPI article, we break down: 💶 ECB reference rates vs. market-based VWAP rates 📊 Which rates work best for accounting, payments, and PnL ₿ Why crypto-to-fiat conversions need a different approach One currency pair. Two very different purposes. Read the full comparison: finfeedapi.com/blog/ecb-exch… #rates

SEC filings are free.... The infrastructure around them isn’t... Search, extraction, XBRL, monitoring, AI-ready retrieval... raw EDGAR access is only the beginning. We break down EDGAR vs a dedicated SEC Data API and where the engineering work actually starts. Read more ↓ finfeedapi.com/blog/sec-edga… #SECAPI #EDGAR #financialdata

A prediction market showing 70%.... it doesn’t necessarily mean you have a strong 70% forecast signal. What about the spread? Liquidity? Volume? Recency? Order book depth? Raw prices are only the beginning... In our new article... we show how to turn prediction market data into probability time series, signal-quality metrics, event alerts, and model-ready datasets using FinFeedAPI. From market prices → to usable forecast signals. Read the full article: finfeedapi.com/blog/predicti… #PredictionMarkets #MarketData #Polymarket #Kalshi #API #AlternativeData

The right financial data can still produce the wrong AI answer... ❌ A filing date is not a reporting period ❌ A prediction market is not just a probability ❓ A ticker without exchange context can be ambiguous ❗ AI agents need data they can interpret, trace, and verify. We explored what that means for FinFeedAPI and how the problem extends across financial data infrastructure.

Data without context isn't useful... A prediction market showing 64% tells you where the probability is now... ... but it doesn't tell you how it got there. ❓ Was it one thin trade? ❓A gradual repricing? ❓Did liquidity shift? ❓What happened around the move? That’s why serious prediction market research needs more than the latest price.... OHLCV. Trades. Quotes. Order books. Historical activity. With FinFeedAPI, you can look beyond the probability and understand the market behind it: finfeedapi.com/blog/predicti… #PredictionMarkets #MarketData #Data

A prediction market moves from 42% → 68%... But what happened in between? When did activity change? When did the market close? Which outcome were you tracking? What happened to its price before resolution? That is why a prediction market is more than a probability... It has a lifecycle... We built a practical guide to tracking that lifecycle with @FinFeedAPI... from market discovery to the final historical record ↓ finfeedapi.com/blog/from-mar… #PredictionMarkets #orderlifecycle

Prediction markets don't live on a single exchange.... @Polymarket @Kalshi @ManifoldMarkets @MyriadMarkets @HyperliquidX Each has its own market structure... API... settlement model... and data format. That makes building applications, research pipelines or AI models across multiple venues more complicated than it should be. We just compared the leading prediction market exchanges and explain what makes each one unique and how FinFeedAPI provides standardized real-time and historical market data through a single API.
