Hyperliquid(HYPE) API Documentation Guide for Algorithmic Trading

TL;DR (Summary)

• Hyperliquid API: Enables algorithmic trading with WebSocket and REST APIs for market data and order management.
• WebSocket & REST APIs: Provide real-time updates and allow for programmatic order placement.
• Key Benefits: Automate trades, optimize strategies, and access market insights for perp futures and spot markets.

Introduction

1.Overview of Hyperliquid API

• WebSocket API: Provides real-time market data for live price feeds, order book updates, and trade execution notifications.
• REST API: Supports functionalities such as placing orders, checking account balances, retrieving market data, and managing open positions.

Key Benefits of Using the Hyperliquid API:

• Programmatic Access: Access market data and order management directly via API calls.
• Real-Time Data: Stream live updates with WebSocket API for instant reactions to price movements.
• Order Placement & Cancellation: Place market or limit orders, and cancel orders programmatically via REST API.
• Integration Flexibility: The API is compatible with various programming languages, enabling you to integrate it into your existing trading systems.

2.How to Get Started with the Hyperliquid API

1. Create an Account and API Key:
   1. Sign up for an account on Hyperliquid and generate an API key from your account settings. This key is used to authenticate your API requests and grant access to the trading platform.
2. Set Up Your Development Environment:
   1. Install the necessary libraries in your preferred programming language. For Python, you can use requests for REST API calls and WebSocket-client for WebSocket data.
   2. If you prefer Node.js or JavaScript, Axios and WebSocket are commonly used.
3. Authenticate Your Requests:
   1. Each API request must include your API key to authenticate the request. The key should be added to the header for all REST API calls.
4. Start Placing Orders:
   1. Once authenticated, you can begin placing market orders, limit orders, and even stop-loss orders. The REST API provides a simple endpoint to place and cancel orders on the Hyperliquid platform.

3.Understanding the WebSocket API

• Real-Time Market Data: Receive updates on price movements, order book changes, and trade execution.
• Order Book Updates: Get continuous updates on bid/ask prices and order book depth to make quick decisions.
• Trade Execution Notifications: Get notified whenever your orders are executed, helping you react to market events in real-time.

4.Managing Orders Using the REST API

• Place Limit Orders: Set a price at which you want to buy or sell, and the system will execute the trade when the market reaches that price.
• Cancel Orders: Easily cancel orders before they’re executed if your strategy changes.

• To place an order, send a POST request with the asset pair (e.g., BTC/USDT), order type (e.g., market order), and quantity.
• If you need to cancel an open order, use the corresponding API endpoint.

5.Integrating Hyperliquid API into Algorithmic Trading Bots

1. Get Market Data: Use WebSocket to stream live price data and order book depth.
2. Analyze Data: Your algorithm analyzes the data in real time to make trading decisions.
3. Place Orders: Use REST API to place buy or sell orders based on your analysis.
4. Monitor Trades: Use the WebSocket API to track whether orders are filled, then adjust strategies accordingly.
