hypernode

Every order, fill, and cancellation on HyperLiquid, streamed in real-time through one WebSocket. Two consensus layers merged into a single feed.

Two layers

Pre-consensus gossip + confirmed node data in one stream

100%

Every order, fill, cancel, rejection — nothing missing

One key, both chains

hypernode is the only HyperLiquid API that bundles data, trading, and infrastructure in one place.

Capability	hypernode	Alternatives
Pre-consensus gossip (cancels/modifies ~1s early)	Included	Not available anywhere
Confirmed order flow (every order, fill, rejection)	Included	Hydromancer ($300+/mo)
L4 order book (individual orders with wallet addresses)	Included	Hydromancer ($300+/mo)
Trading execution (place, cancel, modify orders)	Included	Build it yourself
EVM RPC (contract reads, tx submission, chain 999)	Included	HypeRPC ($2,000/mo)
54 REST endpoints (market data, user state, DeFi)	Included	Partial coverage elsewhere

Starts at $50/mo. One pn_live_ key works across everything.

The unified stream

hypernode merges two data sources that nobody else combines:

Pre-consensus — cancel and modify actions from the gossip protocol, before validators commit them. ~1 second ahead of the public API.
Confirmed — every order placement, fill, cancellation, and rejection after a block commits.

Every event is tagged consensus: "pre" or consensus: "confirmed" so you always know what you’re looking at. ~6,500 events per second on mainnet. Filter down to exactly what you need.

Quick start

import WebSocket from "ws";

const ws = new WebSocket("wss://hyper.polynode.dev/ws?key=YOUR_KEY");

ws.on("open", () => {
  ws.send(JSON.stringify({
    action: "subscribe",
    filters: { action_types: ["order", "fill"] }
  }));
});

ws.on("message", (raw) => {
  const event = JSON.parse(raw.toString());
  console.log(event.consensus, event.type, event.asset, event.data.px);
  // "confirmed" "order" "BTC" "74400.0"
  // "confirmed" "fill" "ETH" "2359.7"
});

What’s in the stream

Type	Layer	What it tells you
`order`	confirmed	New resting limit order with price, size, wallet
`order_filled`	confirmed	Order filled immediately
`order_canceled`	confirmed	Order was canceled
`order_rejected`	confirmed	Order rejected (margin, price, balance)
`fill`	confirmed	Trade execution with PnL, fees, direction
`cancel`	pre	Cancel submitted before block commit
`cancelByCloid`	pre	Cancel by client order ID
`batchModify`	pre	Order modification with new price/size

Subscribe to "order" to get all order lifecycle events. See Event Format for the complete reference.

Batch queries

Query position state, orders, or portfolios for up to 10,000 wallets in a single request. Average latency: 0.12ms per wallet. Built for copy trading platforms, portfolio trackers, and whale monitoring.

curl -X POST https://hyper.polynode.dev/v2/batch/clearinghouse-states \
  -H "x-api-key: YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"users": ["0x...","0x...","0x..."]}'

Four batch endpoints: clearinghouse-states, spot-clearinghouse-states, open-orders, portfolios. See Batch Queries for the full spec.

REST API

54 endpoints for trading, market data, user state, and DeFi on HyperLiquid.

# L4 order book — every individual order with wallet address
curl -H "x-api-key: YOUR_KEY" "https://hyper.polynode.dev/v2/l4book?coin=BTC"

# User positions and margin
curl -H "x-api-key: YOUR_KEY" "https://hyper.polynode.dev/v2/user/state?address=0x..."

# Cross-venue funding rate comparison
curl -H "x-api-key: YOUR_KEY" "https://hyper.polynode.dev/v2/funding-rates"

Authentication

hypernode uses the same API keys as polynode. If you have a polynode account on the Growth plan or above, your pn_live_ key works on hypernode automatically. Sign up at polynode.dev to get started.
