What is Dome API?
Dome was a prediction-market data API that aggregated Polymarket and adjacent venues with broader category coverage than crypto-only competitors. Teams that built on Dome typically wanted unified access to crypto, sports, and economics markets through a single endpoint.
Why look at Resolved Markets as an alternative?
Resolved Markets covers the same breadth Dome users expect — crypto (BTC, ETH, SOL, XRP), sports (NBA, NFL, EPL), economics (FOMC, NFP), weather (~30 markets), and Hyperliquid perpetual futures — and adds high-frequency capture (~20 Hz crypto), full historical archive (no retention cliff), WebSocket streaming, and a native MCP server for AI agents. The ClickHouse backend keeps queries fast at scale.
What is the migration path from Dome to Resolved Markets?
Three-step migration: (1) sign up at resolvedmarkets.com and generate a Pro API key, (2) replace base URL with https://api.resolvedmarkets.com and add X-API-Key header, (3) map endpoints — markets list, live orderbook, historical snapshots, and market summary all have direct equivalents. Full mapping in our /docs reference.
Does Resolved Markets cover the same sports leagues?
Yes — NBA, NFL, EPL game-outcome markets are tracked at ~2 Hz with full bid/ask depth. Other leagues are added as Polymarket lists them.
Do you have economics and weather coverage?
Yes. Economics: FOMC rate decisions, Nonfarm Payroll. Weather: ~30 city temperature markets, hurricane and climate markets. Both categories are queryable through the same /v1/markets/* endpoints — pass ?category=economics or ?category=weather.
