Hyperliquid Perps Trading

Installation

# Check if already installed
which byreal-perps-cli && byreal-perps-cli --version

# Install
npm install -g @byreal-io/byreal-perps-cli

Credentials & Permissions

• All trading commands require account initialization via byreal-perps-cli account init before any trading operations
• Read-only commands (account info, position list, order list, account history): Require initialized perps account
• Write commands (order market, order limit, order cancel, position close-market/close-limit/close-all, position leverage): Require initialized perps account with valid agent wallet
• Signal commands (signal scan, signal detail): No account required — uses public market data only
• Perps agent keys are stored locally in the byreal data directory with strict file permissions (mode 0600)
• The CLI never transmits private keys over the network — keys are only used locally for transaction signing
• AI agents should never ask users to paste private keys in chat; always direct them to run byreal-perps-cli account init interactively

WebSocket / API Fallback

Some commands (account info, position list, position close-market, position close-limit, position close-all) use WebSocket subscriptions to fetch real-time data. If the WebSocket connection fails or times out, the CLI automatically falls back to HTTP API calls. No user action is needed.

If a command returns a connection error:

1. The CLI will retry via HTTP API automatically; if it still fails, the issue is likely network connectivity or Hyperliquid API downtime.
2. Check network connectivity: curl -s https://api.hyperliquid.xyz/info -X POST -H 'Content-Type: application/json' -d '{"type":"meta"}'
3. For testnet, check: curl -s https://api.hyperliquid-testnet.xyz/info -X POST -H 'Content-Type: application/json' -d '{"type":"meta"}'
4. If HTTP API also fails, the Hyperliquid service may be temporarily unavailable — retry after a short wait.

Hard Constraints

1. -o json only for parsing — when showing results to the user, omit it and let the CLI's built-in tables render directly. Never fetch JSON then re-draw tables yourself.
2. Never display private keys — use keypair paths only
3. Never call the SDK directly — do NOT write node -e / tsx -e scripts that import or require packages like @nktkas/hyperliquid or viem. Always use byreal-perps-cli commands to interact with Hyperliquid. The SDK is bundled inside the CLI; calling it externally causes CJS/ESM compatibility errors.
