Dome API Alternative

Dome API alternative — Resolved Markets covers the same breadth and adds depth

Teams that built on Dome wanted unified Polymarket data across crypto, sports, economics, and weather through a single key. Resolved Markets ships exactly that: 100+ markets, ~20 Hz crypto capture, full bid/ask depth, full historical archive, WebSocket streaming, an MCP server for AI agents, and a ClickHouse backend for analytical queries at scale.

Three-step migration from Dome

  1. Sign up and generate a Pro key. Visit /api-keys, create an rm_-prefixed key, and store it in your environment as RM_API_KEY.
  2. Replace base URL and auth header. Swap your Dome base URL with https://api.resolvedmarkets.com and pass X-API-Key: rm_your_key on every request.
  3. Map endpoints. Markets list → /v1/markets/live. Live orderbook → /v1/markets/:id/orderbook. Historical snapshots → /v1/markets/:id/snapshots. Aggregated stats → /v1/markets/:id/summary. Full reference at /docs.

Example — pull Polymarket NBA orderbook

curl -s "https://api.resolvedmarkets.com/v1/markets/live?category=sports&subcategory=NBA" \
  -H "X-API-Key: rm_your_key" | jq '.markets[0].condition_id'

curl -s "https://api.resolvedmarkets.com/v1/markets/<condition_id>/orderbook" \
  -H "X-API-Key: rm_your_key" | jq '{up_bid: .up.best_bid, up_ask: .up.best_ask}'

Frequently asked questions

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.
