Package Exports

hyperliquid-ts
hyperliquid-ts/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (hyperliquid-ts) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

hl-sdk 🍧

An unofficial TypeScript SDK for interacting with the Hyperliquid API.

Installation

npm install hyperliquid-ts

Usage

import { HyperliquidAPI } from 'hyperliquid-ts';

const api = new HyperliquidAPI('YOUR_PRIVATE_KEY');

// Example: Get all mids
api.info.getAllMids().then(allMids => {
  console.log(allMids);
});

Note: Private key is optional but required for authenticated endpoints.

APIs

The SDK is structured into several major components/classes covering the main HL APIs:

info: General information endpoints
- general: General market information
- spot: Spot market information
- perpetuals: Perpetuals market information
exchange: Trading and account management endpoints
subscriptions: WebSocket subscriptions
custom: Custom utility methods and endpoints

Info API

Access general market information:

// Get all mids
api.info.getAllMids();

// Get L2 order book
api.info.getL2Book('BTC-PERP');

// Get user open orders
api.info.getUserOpenOrders('USER_ADDRESS');

// Get trade info
const oid = 123456
api.info.getTradeInfo('USER_ADDRESS', oid);

Perpetuals Info API

Access information specific to perpetual markets:

// Get perpetuals metadata
api.info.perpetuals.getMeta();

// Get perpetuals metadata and asset contexts
api.info.perpetuals.getMetaAndAssetCtxs();

// Get user's perpetuals clearinghouse state
api.info.perpetuals.getClearinghouseState('USER_ADDRESS');

// Get user funding information
api.info.perpetuals.getUserFunding('USER_ADDRESS', startTime, endTime);

// Get user non-funding ledger updates
api.info.perpetuals.getUserNonFundingLedgerUpdates('USER_ADDRESS', startTime, endTime);

// Get funding history for a specific coin
api.info.perpetuals.getFundingHistory('BTC-PERP', startTime, endTime);

Spot Info

// Get spot metadata
api.info.spot.getSpotMeta();

// Get spot clearinghouse state for a user
api.info.spot.getSpotClearinghouseState('USER_ADDRESS');

// Get spot metadata and asset contexts
api.info.spot.getSpotMetaAndAssetCtxs();

Leaderboard API

Access and filter the trading leaderboard:

// Get the current leaderboard
api.leaderboard.getLeaderboard();

// Get filtered and sorted leaderboard
api.leaderboard.getFilteredAndSortedLeaderboard({
  timeWindow: 'day',
  minAccountValue: 1000,
  minVolume: 10000,
  maxTrades: 100
}, 'pnl');

// Get extended trader information
api.leaderboard.getExtendedTraderInfo(traderEntry, 'week');

// Get a trader's best trade
api.leaderboard.getBestTrade('TRADER_ADDRESS', 'month');

Advanced usage

The Leaderboard API also provide methods for more detailed analysis:

// Get a trader's trade count
api.leaderboard.getTraderTradeCount('TRADER_ADDRESS', startTime, endTime);

// Get a trader's open positions
api.leaderboard.getTraderOpenPositions('TRADER_ADDRESS');

Note: The leaderboard data is cached for 24 hours to improve performance. You can manually clear the cache if needed:

await api.leaderboard.clearCache();

Symbol Conversion

The SDK now includes a SymbolConverter to handle any differences between exchange and internal symbol representations:

// Convert from exchange to internal format
api.info.convertSymbol('BTC-0', 'internal');

// Convert from internal to exchange format
api.info.convertSymbol('BTC-PERP-0', 'reverse');

// Get all available assets
const assets = api.info.getAllAssets();
console.log(assets.perp); // List of perpetual assets
console.log(assets.spot); // List of spot assets

Please refer to SYMBOLS.md for more detailed info

Exchange API

Manage orders and perform account actions:

// Place an order
api.exchange.placeOrder({
  coin: 'BTC-PERP',
  is_buy: true,
  sz: 1,
  limit_px: 30000,
  order_type: { limit: { tif: 'Gtc' } },
  reduce_only: false
});

// Cancel an order
api.exchange.cancelOrder({
  coin: 'BTC-PERP',
  o: 123456 // order ID
});

// Transfer between spot and perpetual accounts
api.exchange.transferBetweenSpotAndPerp(100, true); // 100 USDC from spot to perp

WebSocket Subscriptions

Subscribe to real-time data:

// Subscribe to all mids
api.subscriptions.subscribeToAllMids(data => {
  console.log('All mids update:', data);
});

// Subscribe to trades for a specific symbol
api.subscriptions.subscribeToTrades('BTC-PERP', trades => {
  console.log('New trades:', trades);
});

// Unsubscribe from trades
api.subscriptions.unsubscribeFromTrades('BTC-PERP', callbackFunction);

Custom Utilities

// Cancel all orders
api.custom.cancelAllOrders();

// Cancel all orders for a specific symbol
api.custom.cancelAllOrders('BTC-PERP');

// Get all tradable assets
const assets = api.custom.getAllAssets();

Error Handling

The SDK uses custom error types. Wrap API calls in try-catch blocks:

try {
  const result = await api.exchange.placeOrder(/* ... */);
} catch (error) {
  if (error instanceof HyperliquidAPIError) {
    console.error('API Error:', error.message, 'Code:', error.code);
  } else {
    console.error('Unexpected error:', error);
  }
}

Rate Limiting

The SDK implements rate limiting to comply with API restrictions. You don't need to manage this manually.

WebSocket Connection

The WebSocket connection is managed automatically. Use connect and disconnect methods if you need manual control:

await api.connect();
// ... perform operations
api.disconnect();

Types

The SDK provides TypeScript types for all API responses and parameters. Import them as needed:

import type { OrderRequest, UserOpenOrders } from 'hyperliquid-ts';
