  summary: High-fidelity orderbook data for Polymarket prediction markets and Hyperliquid perpetual futures, plus a backtesting engine and saved-strategy store.
  description: 'REST API for live and historical orderbook snapshots, trades, platform statistics, and event-driven strategy backtesting. Public endpoints (health, public-stats, payment packs) require no authentication. Data endpoints require an `X-API-Key` header where the key starts with `rm_` — get one at https://resolvedmarkets.com/api-keys. Account, subscription, and payment endpoints require a Clerk browser session and are not callable with an API key. WebSocket endpoints exist at `/ws/orderbook` and `/ws/chat` (see Servers / x-websocket).


    Probabilities are USDC prices in 0.01..0.99. Each Polymarket binary market has two tokens — UP (Yes outcome) and DOWN (No outcome) — each with its own orderbook. UP price + DOWN price ≈ 1.00.'
