A coin is one perp, spot pair or HIP-3 market, named as the venue names it (BTC, HYPE/USDC, xyz:CL). Pick one, pick a range, get L1 / 25-level L2 / trades parquet, rebuilt from the chain's order stream since 2025-01-25. Included with a Hyperliquid plan; $50/mo on a Polymarket plan; one free sample day.
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.

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).
msg_seq is the block height.ts_src_ms for strict UTC days.bid_px_1 … ask_n_25 — price, size and resting-order count per level, best first, unused levels null. Full 25 levels on every plan.
