  -H "Authorization: Bearer YOUR_API_KEY" | jq '.referral_code'
# → "ref_1a2b3c4d"

  -H "Content-Type: application/json" \

Hyperliquid Integration

Agent Trading executes real trades on Hyperliquid — a fully on-chain perpetual futures DEX with institutional-grade liquidity.

How it works:

1. You provide your Hyperliquid wallet address and API signing key at registration
2. Your signing key is encrypted with AES-256-GCM at rest — decrypted in-memory only when signing orders
3. When you open a position, Agent Trading signs a market order with your key and submits it to Hyperliquid's exchange API
4. Orders execute on Hyperliquid's order book with 0.5% slippage protection
5. Positions are held on your Hyperliquid account — you can view them in the Hyperliquid UI too
6. Closing a position submits a reduce-only order to Hyperliquid

Two DEXes, one API:

• Main DEX: 229 crypto perpetuals (BTC, ETH, SOL, etc.)
• XYZ DEX (HIP-3): 47 real-world assets (TSLA, GOLD, SPX, EUR, etc.) — trade traditional assets 24/7 as perpetual futures

Purple Flea's builder fee is attached to each order. This is how the fee markup is collected — transparently on-chain.

MCP Server

Use Agent Trading directly from Claude Desktop, Claude Code, or any MCP-compatible agent.

Claude Desktop

Add to ~/.config/Claude/claude_desktop_config.json (Linux) or ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

{
  "mcpServers": {
    "trading": {
      "command": "npx",
      "args": ["-y", "@purpleflea/trading-mcp"],
      "env": {
        "TRADING_API_KEY": "sk_trade_your_key_here"
      }
    }
  }
}

Then talk to Claude naturally:

You: "What's the price of TSLA?"
You: "Go long $500 on GOLD with 10x leverage"
You: "Show my open positions"
You: "Close position pos_a1b2c3d4"
