Crypto & Stock Market Data (Node.js)

What This Skill Does

The Crypto & Stock Market Data skill provides OpenClaw agents with professional-grade access to global financial markets. It acts as a comprehensive analytical engine, allowing users to query real-time valuations, market capitalization, historical price trends, and fundamental asset metadata for both cryptocurrencies and publicly traded stocks. By utilizing a zero-dependency Node.js implementation, the skill ensures high performance and reliable connectivity to financial data streams without the overhead of heavy npm modules. Whether you are tracking the latest price action on Bitcoin, analyzing the market cap of top-tier altcoins, or researching the corporate profile of S&P 500 companies, this tool delivers the necessary metrics directly to your terminal or agent workflow.

Installation

To integrate this skill into your environment, run the following command within your terminal or OpenClaw interface:

clawhub install openclaw/skills/skills/dagangtj/guanjia-crypto-market-data

Ensure you have Node.js installed on your machine. No additional environment variables or external API keys are required for the free tier, making setup instantaneous.

Use Cases

• Investment Monitoring: Set up automated alerts or snapshots of your portfolio performance using real-time price feeds.
• Market Analysis: Compare historical candlestick (OHLC) data for technical analysis or sentiment validation.
• Asset Discovery: Use the search utilities to identify ticker symbols or coin IDs for assets that have recently entered the market.
• Financial Reporting: Generate summary dashboards using the global market data and treasury holdings endpoints to track institutional crypto adoption.

Example Prompts

1. "Check the current market price of Bitcoin and Ethereum in JPY and provide their 24-hour volume."
2. "Search for the latest stock data for Apple and Microsoft, including their company profile summaries."
3. "Show me the top 20 cryptocurrencies ranked by market cap and identify which ones are currently trending."

Tips & Limitations

• Asset IDs: Use the search tools (search_stocks.js or search_coins.js) if you are unsure of the exact ticker or ID, as query parameters are case-sensitive.
• Currency Support: While USD is the default, most endpoints support multi-currency conversion—use the --currency flag to see the full list via get_supported_currencies.js.
• Rate Limits: As this uses the free tier, please implement logic to prevent high-frequency spamming if you are running scripts in a continuous loop to avoid temporary connection timeouts.
