Overview
Dome provides unified APIs and SDKs that normalize prediction market data from multiple platforms into a single interface. Instead of integrating separately with Polymarket’s CLOB API, Kalshi’s REST API, and other platform-specific endpoints, agents can use Dome’s single API key and standardized data format to access markets across the ecosystem.
Key Features
Multi-platform normalization — Access data from Polymarket, Kalshi, Limitless, and other platforms through one API with consistent schemas.
Real-time and historical data — Live market prices and order books plus historical data for backtesting agent strategies.
Single API key — One authentication credential for all platforms, simplifying agent configuration.
Standardized format — Consistent JSON schemas across platforms, eliminating the need to write platform-specific parsers.
Agent-Friendliness

| API quality | Good — clean REST with consistent schemas |
| Multi-platform | Excellent — single key for multiple exchanges |
| Data coverage | Good — real-time and historical |
| JSON support | Yes — standardized across platforms |
| Use case | Data consumption and cross-platform comparison |
Best For
Arbitrage agents that need to compare prices across Polymarket and Kalshi simultaneously. Also useful for any agent that wants to scan the entire prediction market ecosystem without maintaining separate integrations for each platform.
