About
Kalshi is a federally regulated derivatives exchange built for quants. Kalshi’s markets are volatile and settle daily, which means even a small edge can be extremely profitable. Trading is fully-cash collateralized, so you can never lose more than you put into a trade, and contracts can be purchased for as little as $0.01.
Kalshi supports trading through its native app (iOS & Android), website, and API. The latter features extensive documentation, open-sources sample code, and live technical support. Getting started with an algorithmic strategy is as easy as `pip3 install kalshi_python`.
The following data is available for free on both the website and API:
* Historical spreads: Use past pricing data to set up back-tests within minutes.
* Low-latency broadcasts: Receive live updates of market price movements and trade executions.
* Economic projections: Build strategies using Kalshi’s proprietary forecasting tools.

About
Predictefy is a prediction-market data and trading infrastructure platform for developers, algorithmic traders, and research teams. Its REST API and SDKs provide a normalized way to retrieve market catalogs, prices, order books, trades, and historical data from supported venues. Users can stream live market updates over WebSockets, compare related markets across venues, and access market-matching and price-discrepancy data. The platform also documents order-building and execution workflows, portfolio and trader analytics, and tools for building automated strategies and AI-agent workflows, including an MCP server. Venue capabilities vary, and some analytics or data features depend on the subscription plan. Predictefy is designed for software teams and traders building research tools, trading bots, market monitors, and applications that use prediction-market data.
