Why not the official API
Limitations of the official historical Hyperliquid data
The official Hyperliquid API is a great starting point, but it has limited historical options. Hydromancer offers a better way — with consistent S3 uploads, unlimited per-wallet data, and most granular orderbook history.

FAQ
Frequently asked questions
What is Reservoir?
Reservoir is Hydromancer's free, forever S3 archive of granular Hyperliquid historical data. It includes all fills (trades, liquidations, ADLs, builder fills, TWAP fills), 1-second OHLCV candles, daily account snapshots, and 20-level L2 orderbook snapshots at 1-minute cadence — covering every HIP-3 deployer and Hyperliquid itself, with complete history from launch.
Why use Hydromancer for Hyperliquid historical data instead of the official API?
The official Hyperliquid API is rate-limited, paginated by recency, and has no S3 archive. Hydromancer provides the most granular data on demand, supports time-range queries, removes pagination limits, and ships a free S3 archive. It's the option chosen by market makers and the biggest apps on Hyperliquid.
Is Reservoir really free?
Yes — free, forever. Data is delivered through AWS S3 in requester-pays mode, so you cover the AWS data-transfer cost on your end. No subscription, no Hydromancer fees.

All Hyperliquid historical endpoints, including userFills, userFillsByTime, userTwapSliceFills, userFunding, userNonFundingLedgerUpdates, builderFills, builderFillsByTime, userTwapSummaries, fundingHistory, historicalOrders, and builderOrdersByTime.
