The complete order-book and trade history of Hyperliquid spot pair @228 (the venue names spot pairs by index): top of book on every change, the 25-level book on every change with resting-order counts, and every fill with the taker's wallet, fee and realized PnL — rebuilt from the chain's own order-event stream, one row per block.
Three parquet files per day plus a quality scorecard. Sizes are this coin's own averages over its 352 days on disk.
hl_l1Best bid and ask with sizes and the spread, one row per block in which the top of book changed, replayed from the chain's own order events — not sampled from a websocket. No consecutive duplicates.
hl_l2The 25-level book on both sides — price, size and the number of resting orders at each level — one row per block in which any of it changed. Wide columns (bid_px_1 … ask_n_25), unused levels null. This is the table the venue's own websocket cannot give you: Hyperliquid pushes l2Book snapshots only, throttled to seconds.
hl_tradesEvery fill the chain executed: price, size, taker side, order id, the taker's wallet, fee and fee token, closed PnL and start position, and the settlement transaction hash. From 2025-03-22 straight from the node's fills tape; before that synthesized from the taker's own fill status (see caveats).
Building this yourself — pulling the chain's order-event archive out of requester-pays S3 and replaying it into books — runs to around $10,000 in egress and compute. Every coin arrives in the same objects, so there is no @228-only shortcut.
A quarter of @228 — every table — is about 1.7 GB. Explorer ($89/mo) and Premium ($199/mo) bought for Hyperliquid include every coin at full book depth; $50/mo adds Hyperliquid to a Polymarket plan. Any free account pulls 2026-08-12 at no cost.
