It covers Hyperliquid perps, Spot, HIP-3 dexes and HIP-4 markets, with Hyperliquid data from 28 July 2025. That is a strong free option for exploring Hyperliquid. The trade-offs are the window and the grain: a minute between book snapshots, and no stored order-level book listed. ## Hydromancer's paid API streams order-level books live From $300 a month, Hydromancer's API adds a live L4 book with the wallet on every resting order, as a REST snapshot refreshed each second and a WebSocket stream per block. It also serves funding, open interest and liquidation history, and HIP-4 outcome data. Its market-wide REST fills cover the last 24 hours. ## 0xArchive stores the book back to 2023 and order by order since March 2026 0xArchive has kept Hyperliquid's 20-level book since 15 April 2023, two years before the July 2025 start Reservoir gives for its Hyperliquid data. Since 10 March 2026 it also stores the order-level book with wallets, and serves the exact book at any timestamp by REST, WebSocket replay or Parquet export. It covers Lighter in the same API, with trades from January 2025 and Lighter's order-level book (L3) from March 2026. The free plan covers the last 30 days on every venue, and Build opens the full archive for $49 a month.
