The most-recent N OHLCV candles (≤5000), in Hyperliquid's candleSnapshot shape. Same per-row pricing as the windowed read ($0.00001 base for main/spot, $0.000025 premium for HIP-3/HIP-4); candles lag ~2 days.

The most-recent N open-interest / funding / ctx rows (≤5000), as {coin, ctx, time}. Priced per row ($0.000025 premium); served live (no lag).

The most-recent N HIP-4 outcome-side rows (≤5000). Priced per row ($0.000025 premium); served live.

Archive coverage for a coin's liquidations over a window (≤7 days): which archived hours hold liquidations and where the gaps are. Warms the cache for everyone after. Priced floor ($0.001) + $0.05 per archived hour examined.

Raw market trades over a time window: the live hot tier (~24h) plus S3 read-through for older history (archive from 2025-05-25), merged. Each row mirrors HL's WsTrade verbatim, including the buyer/seller addresses (`users`) and the trade `hash`. Rows come oldest-first (by time, then tid) for forward paging, unlike Hyperliquid's newest-first recentTrades. Priced per asset-hour ($0.015 base, $0.03 HIP-3/HIP-4) plus $0.05 per uncached archive hour pulled (warms the cache); ≤24 asset-hours/request.

Derived two-sided open interest for a HIP-4 outcome market, per minute (circulating-supply times mark, summed over both sides). Priced per row ($0.000025 premium); served live. Takes the integer outcome id (e.g. 100).

Forced-liquidation tape over a time window, reconstructed from the node-fills archive (Hyperliquid has no public liquidations feed). Each row is the liquidated user's fill as Hyperliquid's userFills WsFill, one per liquidated trade id, with the nested liquidation object {liquidatedUser, markPx, method market|backstop}. Priced per asset-hour ($0.005 base, $0.01 HIP-3/HIP-4) plus $0.05 per uncached archive hour pulled; up to 24 asset-hours/request, available ~2h after the hour closes.

OHLCV candles over a window: main, spot, HIP-3 (e.g. xyz:AAPL, xyz:SP500) and HIP-4 outcome markets; intervals 1m to 1d. Priced per row ($0.00001 base for main/spot, $0.000025 premium for HIP-3/HIP-4). Rows use Hyperliquid's candleSnapshot keys (t, T, s, i, o, c, h, l, v, n). Paginate with the X-Next-Start header (≤5000 rows/page): it is the last `t` plus the interval in ms, the next start; keep going while it is present, even after a short page. Candles lag ~2 days (reconstructed from the archive); omit start/end for the most-recent page.

HIP-4 outcome-side mark / mid (implied probability) / circulating-supply / volumes over a window. Priced per row ($0.000025 premium); paginate with the X-Next-Start header (≤5000 rows/page); served live. Coin is the encoded '#<10*outcome+side>' (e.g. %231000).

Open interest / funding / mark / oracle / mid / volumes over a window: the OI & funding history Hyperliquid keeps no endpoint for. Perpetuals only: main, or a HIP-3 dex via `dex`. Rows are Hyperliquid's activeAssetCtx {coin, ctx} plus `time` (epoch seconds). Priced per row ($0.000025 premium); paginate with the X-Next-Start header (≤5000 rows/page): it is the last `time` plus 60, the next start. Served live (no lag).
