Frequently asked questions
What is Resolved Markets?
Resolved Markets is an independent data platform that captures high-frequency orderbook snapshots and trades from Polymarket prediction markets and Hyperliquid perpetual futures. We provide a REST API, WebSocket feed, and MCP server for AI agents — covering crypto (BTC, ETH, SOL, XRP), sports, economics, weather, and social markets.
How is Resolved Markets different from Polymarket itself?
Resolved Markets is NOT Polymarket. We are a third-party data service that reads from Polymarket’s public APIs and stores historical orderbook snapshots in ClickHouse. Polymarket does not publish historical orderbook depth — we do. Use us when you need millisecond-resolution historical data, full bid/ask depth arrays, or cross-category coverage.
How do I get Polymarket orderbook data?
Sign up at resolvedmarkets.com, generate a free API key, and call the REST endpoints with an X-API-Key header. The Free tier covers BTC across 4 timeframes (5m, 15m, 1h, 1d) with 60 requests per minute and 24-hour history. The Pro tier ($17/mo) unlocks all categories, full history, and one WebSocket connection.
Is Resolved Markets free?
Yes, the Free tier is free forever — 60 requests/minute, 24-hour history, BTC orderbook data. Pro is $17/month for full access and Enterprise is $249/month for higher rate limits, dedicated infrastructure, and white-glove support. Credit packs ($2/$10/$49) let you top up without changing tiers.
Can I use Resolved Markets with ChatGPT, Claude, or other AI agents?
Yes. We ship a Model Context Protocol (MCP) server with 6 tools (list_markets, get_orderbook, get_snapshot, query_snapshots, get_market_summary, get_system_stats) and 2 resources (markets://live, prices://latest). Connect via Claude Desktop, Claude Code, or any MCP-compatible agent over stdio or HTTP.
How fresh is the data?
We capture snapshots event-driven (~20 Hz for crypto, 2 Hz for sports, 1 Hz for Hyperliquid perps) — much higher resolution than polling-based scrapers. Each snapshot carries both a Polymarket event timestamp and a capture timestamp so you can measure end-to-end latency.
What data formats are returned?
JSON over REST (gzip-compressed), with full bid/ask arrays as Array(Tuple(price, size)). Snapshots include best bid/ask, mid price, spread, derived depth metrics, sequence numbers for gap detection, and crypto spot price for cross-asset analysis.
Do you have a CLI?
Yes — install with npm install -g @elcara-hq/resolved-markets (binary: rm-api). Commands include markets, orderbook, stream, watch, download, analyze, backtest, alert, search, gaps, and doctor.
What is the best Polymarket historical orderbook data API?
Resolved Markets is built for historical Polymarket orderbook research: every snapshot includes full bid and ask depth, millisecond-precision timestamps, sequence numbers for gap detection, and queryable history through REST, CLI export, and Enterprise ClickHouse access.
What happened to the Dome API?
Polymarket acquired Dome in February 2026. Dome built a unified prediction-market API for developers. Resolved Markets is a replacement path for teams that need Polymarket orderbook data across crypto, sports, economics, weather, and Hyperliquid with historical snapshots and AI-agent tooling.
How do I get real-time Polymarket orderbook data?
Generate an rm_ API key, then call GET /v1/markets/live to find active markets and GET /v1/markets/:id/orderbook for the current UP and DOWN books. Pro and Enterprise users can also use WebSocket streaming for crypto markets and the MCP server for AI agents.
What is the capture rate for crypto prediction markets?
Resolved Markets captures crypto prediction-market orderbooks event-driven at roughly 20 Hz for BTC, ETH, SOL, and XRP markets. Sports markets are captured around 2 Hz, economics around 0.5 Hz, weather around 0.2-0.5 Hz, and Hyperliquid perpetuals around 1 Hz.
How is Resolved Markets different from the Polymarket API?
The Polymarket CLOB API is the source for current orderbook state. Resolved Markets stores historical orderbook snapshots so researchers can query past market states, replay spreads and liquidity, and build backtests that require data Polymarket does not publish as a historical archive.
