connectors-available

What This Skill Does

The connectors-available skill is a diagnostic and discovery tool for OpenClaw users, designed to interface with the Hummingbot API to verify exchange connectivity and retrieve specific trading parameters. This skill performs two core functions: it tests the accessibility of various exchange connectors (spot or perpetual) based on your current network location and creates a centralized registry of trading rules. By generating a comprehensive data/trading_rules.json file, the skill ensures that subsequent trading strategies operate with accurate knowledge regarding minimum order sizes, price increments, and supported order types (Limit vs. Market). It acts as a prerequisite for any automated trading deployment, preventing "order rejected" errors by validating exchange-specific constraints before execution begins.

Installation

To install this skill, use the ClawHub CLI inside your OpenClaw environment: clawhub install openclaw/skills/skills/fengtality/connectors-available

Ensure your Hummingbot API is active (defaulting to localhost:8000). You must configure your environment variables to allow the scripts to authenticate. Create or update your .env file with the following keys:

• HUMMINGBOT_API_URL (default: http://localhost:8000)
• API_USER
• API_PASS The skill will automatically search for these credentials in local project directories and your home folder during execution.

Use Cases

• Pre-deployment Audits: Verify which exchanges are reachable from your server location before setting up a strategy.
• Asset Discovery: Quickly look up how a specific token is traded across multiple exchanges to compare liquidity and order constraints.
• Risk Management: Validate the 'Min Order' and 'Min Price Increment' values to ensure your position sizing logic complies with exchange requirements.

Example Prompts

1. "Run a diagnostic on all available perpetual connectors to see what is accessible from here."
2. "Search for all trading rules for SOL on the connected exchanges."
3. "Only test the Kraken and Hyperliquid connectors and update my local trading rules file."

Tips & Limitations

• Timeout Sensitivity: The --timeout parameter is crucial; if you are on a slow connection or behind a restrictive VPN, consider increasing the timeout value in the script command.
• Local Cache: Remember that data/trading_rules.json is a snapshot. If you notice an exchange is not appearing, re-run the test_all.sh script to refresh your local cache.
• Scope: This skill relies entirely on the Hummingbot API. If the API is not responding or your credentials are invalid, the skill will fail to retrieve any data.
