Dome API

Dome is a data API platform focused on providing developers and traders with access to real-time and historical data from decentralized and centralized prediction markets such as Polymarket and Kalshi. It offers comprehensive orderbook data, enabling users to build analytics, trading bots, or market insights tools with reliable and up-to-date information. Dome’s APIs are designed to be free and easy to integrate, lowering the barrier for developers to access complex market data without managing infrastructure or scraping data themselves.

The platform targets analytics developers, financial institutions, and DeFi teams who require granular prediction market data for decision-making, risk assessment, or building derivative products. Dome aggregates data from multiple sources, normalizes it, and delivers it through RESTful APIs with clear documentation. This approach helps solve the problem of fragmented and inconsistent prediction market data, which is often difficult to access in real time or historically.

Getting started with Dome involves signing up for API access and reviewing the comprehensive documentation that covers endpoints for orderbooks, trades, and market metadata. The free tier allows developers to experiment and build prototypes without upfront costs. Dome’s focus on prediction markets differentiates it from general market data providers by offering specialized, high-quality data tailored for this niche. This makes it a practical choice for teams building prediction market analytics, trading strategies, or integrating market data into DeFi protocols.
