Hyperliquid

Managed Hyperliquid Node Infrastructure

Full-stack data access to Hyperliquid L1. Premium SSD-backed nodes in two regions, serving four protocols through hardened Nginx gateways with TLS, API key auth, and tiered rate limiting.

JSON-RPC

rpc.aleatoric.systems rpc-jp.aleatoric.systems

Standard EVM JSON-RPC proxy to local node's :3001/evm endpoint. Full eth_* namespace support. Compatible with ethers.js, web3.py, viem, and all EVM tooling.

Port 443 (Nginx) Auth: x-api-key header Rate: 5000 req/s per key

gRPC (Protocol Buffers)

hl.grpc.aleatoric.systems:443 jp.grpc.aleatoric.systems:443

Low-latency streaming via hypercore.bridge.v1.PriceService. Supports GetMidPrice, StreamMids, GetBlockNumber, and StreamLiquidations. Microsecond-precision timestamps with upstream/ingest/publish latency tracking.

HTTP/2 + TLS Auth: x-api-key or Bearer metadata Subscriptions: allMids, trades, l2Book

Unified Stream (SSE)

unified.grpc.aleatoric.systems unified-jp.grpc.aleatoric.systems

Pre-decoded event fanout via Server-Sent Events. HyperCore + HyperEVM events including liquidation warnings, L4 deltas, transfers, and consensus pulse (block height + gas deltas + P2P latency).

SSE over HTTPS Tiered: public (100rpm) to quant (5000rps) Target latency: 500µs

Disk-Sync WebSocket

disk.grpc.aleatoric.systems disk-jp.grpc.aleatoric.systems

Raw Hyperliquid replica command hex feed over WebSocket. Full-fidelity node output for custom indexing, replay infrastructure, and low-level analysis. Quant tier only.

WSS Auth: x-api-key or ?api_key= param Quant only
