Install

Use Node.js 22.12 or later, or Bun 1.3.3 or later.

npm install @bloxwap/hyperliquid

Read a price

Create an HTTP client and request market data. This example uses mainnet and needs no wallet or API key.

// 1. Import module
import { HttpTransport, InfoClient } from '@bloxwap/hyperliquid';

// 2. Set up client with transport
const transport = new HttpTransport();
const info = new InfoClient({ transport });

// 3. Query data
const mids = await info.allMids(); // mid-prices for all coins
console.log(mids.BTC);

const book = await info.l2Book({ coin: 'BTC' }); // L2 order book snapshot

For testnet, use new HttpTransport({ isTestnet: true }).

The SDK site brings setup, guides, and API documentation together:

• Installation and quick start — runtime requirements, React Native setup, and client examples.
• Guides — market orders, agent wallets, vaults, and browser wallets.
• Clients — HTTP requests, exchange actions, and WebSocket subscriptions.
• Known documentation drift — verified differences between official documentation, live API behavior, and SDK types.

The SDK is a fork of nktkas/hyperliquid, released under the MIT license.
