# Hyperliquid Historical Coverage Expands with New Builder and WebSocket APIs

*Published June 16, 2026*

![Hyperliquid Historical Coverage Expands with New Builder and WebSocket APIs](https://www.datocms-assets.com/86369/1781632554-goldrush-hyperliquid-api-expansion.jpg)

GoldRush now gives builders deeper HyperCore history and more ways to stream live Hyperliquid activity.

Historical HyperCore coverage starts at block `606,858,021 (2025-05-25T14:32:53Z)`. From that point onward, fills, orders, trades, funding, and ledger events are retained and queryable through GoldRush.

This expands historical access for high-volume `/info` types like `userFillsByTime` and `candleSnapshot`, so builders can query beyond the public Hyperliquid retention window using GoldRush’s dedicated HyperCore historical store.

We’ve also added two GoldRush-native builder attribution endpoints to the Hyperliquid Info API:

* `builderFills` - fetch the most recent fills attributed to a builder address.
* `builderFillsByTime` - fetch builder-attributed fills over a historical time window.

For real-time use cases, the Hyperliquid WebSocket API now includes three new HyperCore streams:

* `userFills` - stream live trade fills for one or more wallets.
* `liquidationFills` - stream a global feed of liquidation fills across HyperCore.
* `userNonFundingLedgerUpdates` - stream live non-funding ledger events, including deposits, withdrawals, transfers, liquidations, vault actions, staking, and rewards.

Wallet-keyed streams **support up to 1,000 HyperCore wallet addresses per subscription** and are priced at `1` credit per minute connected.
