GoldRush is the complete, low-latency data layer for Hyperliquid - the indexer and data provider that aggregates everything you need to build on Hyperliquid - HyperCore, HIP-3, HIP-4, and HyperEVM - under one API key.
Hyperliquid - HyperCore historical coverage starts at .Every data type (fill, order, trade, funding, and ledger event) from that block onward is retained and queryable.

Drop-in Hyperliquid API replacement

Drop-in replacement for both the public /info REST API and /ws WebSocket. Change one URL to remove rate limits and unlock more data. Hosted at hypercore.goldrushdata.com.

Real-time Streaming

Wallet firehose, OHLCV for every HIP-3 and HIP-4 market the moment it goes live, and pre-decoded liquidations and vault events.

HyperEVM coverage

Token balances, transfers, approvals, NFTs, and gas for HyperEVM - same shape as every other EVM chain on GoldRush.

​
Drop-in coverage: REST + WebSocket

GoldRush replaces both of Hyperliquid’s public surfaces with a single host - hypercore.goldrushdata.com. Same request bodies, same response shapes, same subscription payloads as the public API. Swap the URL, add the GoldRush API key, and your existing clients work unchanged - with no rate limits and no per-IP subscription caps.
Auth differs between REST and WebSocket. REST takes an Authorization: Bearer <GOLDRUSH_API_KEY> header. The WebSocket takes a ?key=<GOLDRUSH_API_KEY> query parameter (most WebSocket clients can’t send headers during the upgrade handshake). Same key for both.

REST /info API

Drop-in replacement for POST https://api.hyperliquid.xyz/info. 17 wire-compatible type values plus GoldRush-native batch endpoints (batchClearinghouseState, batchSpotClearinghouseState) for up to 50 wallets per call.

WebSocket API

Drop-in replacement for wss://api.hyperliquid.xyz/ws with no 1000-subscription-per-IP cap. Subscribe to l2Book (aggregated snapshots - omit coin to stream every asset on one subscription), the GoldRush-native l2BookDiff (snapshot plus per-block diffs of changed {px, sz, n} levels - accepts a single coin, a list, or wildcard), or the GoldRush-native l4Book (per-order snapshot plus per-block diffs with user, oid, cloid, and trigger metadata exposed).

​
Hyperliquid API limitations addressed by GoldRush

The public Hyperliquid /info API is generous, but it has hard limits that most production apps run into:
  • 1200 weight/min/IP rate limits per address.
  • 1000 WebSocket subscriptions per IP - not enough to track every active trader.
  • WebSocket subscription filters are required - every subscription must specify an asset (e.g. coin on l2Book), forcing per-asset fan-out that burns through the 1000-subscription cap. GoldRush makes these filters optional so a single wildcard subscription streams every asset.
  • No batch address endpoints - account-state calls are single-wallet only; GoldRush adds batchClearinghouseState and batchSpotClearinghouseState for up to 50 wallets per request.
  • userFills capped at ~10,000 rows - active traders blow through that in weeks.
  • Liquidations buried inside fills as a thin stub; vault, staking, and delegation data arrives untyped.
  • HIP-3 and HIP-4 discovery is manual - candleSnapshot is poll-based and effectively limited to mainstream markets.
  • No HyperEVM concept at all - DEXes, NFT mints, and lending live on chain 999 and the /info API doesn’t see them.
GoldRush closes every one of these gaps. See GoldRush vs Hyperliquid public API for the full breakdown.

What’s included

​
Infrastructure

GoldRush runs its own Hyperliquid indexing infrastructure - purpose-built to be the fastest, most reliable Hyperliquid data provider for production apps and quant desks:
  • Dedicated Hyperliquid nodes in Tokyo - co-located with Hyperliquid’s validator infrastructure for low-latency reads.
  • Private backbone for high-throughput data ingestion.
  • No rate limits - bypass the public /info and WebSocket constraints entirely.
  • Full historical backfill - every fill, funding payment, and ledger event back to HyperCore . HyperEVM coverage goes back to genesis.
