What This Skill Does

CryptoWatch is a powerful, lightweight OpenClaw agent skill designed to provide real-time monitoring and alerting for the cryptocurrency market. By leveraging the CoinGecko API, this tool allows users to fetch up-to-the-second pricing data for over 100 cryptocurrencies without the need for an API key. Beyond simple price checks, the skill offers sophisticated market intelligence, including 24h/7d/30d performance tracking, market cap rankings, and automated price breakthrough alerts. It effectively turns your OpenClaw agent into a personal market analyst that watches the charts 24/7, ensuring you never miss a pump or a critical market movement.

Installation

To integrate this skill into your environment, use the OpenClaw management CLI. Run the following command in your terminal: clawhub install openclaw/skills/skills/gztanht/cryptowatch

Alternatively, you can initialize it directly via NPM: npx @gztanht/cryptowatch. Ensure you have Node.js installed, and you can further customize your watch list by editing config/coins.json in your local project directory to include specific project IDs from CoinGecko.

Use Cases

• Active Trading: Investors use the breakthrough alerts to trigger notifications when BTC or ETH hits specific entry or exit price points, allowing for timely decision-making.
• Market Analysis: Researchers can utilize the ranking tools to analyze market leaders by volume or market capitalization over various timeframes.
• Portfolio Monitoring: The ability to track a custom watchlist of coins allows users to keep a close eye on their specific holdings in USD, CNY, or other local currencies.
• Alerting Automation: Set 'set and forget' thresholds for volatile assets, letting the agent handle the monitoring and alerting, reducing the need for constant manual screen time.

Example Prompts

1. "CryptoWatch, what is the current price of Bitcoin and Solana, and how much have they moved in the last 24 hours?"
2. "Set an alert for ETH; notify me immediately if the price drops below 2800 USD."
3. "Show me the top 10 cryptocurrencies by market cap for this week, sorted by the highest 7-day gainers."

Tips & Limitations

• Rate Limiting: The free CoinGecko tier supports 10-50 calls per minute. Avoid flooding the service with automated loops faster than the allowed rate.
• Data Latency: While extremely fast, please note there is an approximate 30-second data delay compared to centralized exchange order books.
• Customization: Always maintain your config/coins.json file properly to avoid tracking irrelevant assets.
• Security: As this is an external API connector, ensure you are running the latest version of the skill to patch any identified vulnerabilities in the dependency chain.
