Price Monitor

What This Skill Does

The Price Monitor skill empowers your OpenClaw agent to act as a sophisticated financial dashboard. By integrating with the CoinGecko API, it enables real-time tracking of cryptocurrency valuations, market capitalization, and 24-hour price fluctuations. Beyond simple data retrieval, this skill provides a robust alert system, allowing users to define specific price thresholds for assets that are automatically monitored. The skill is designed to handle multiple currencies, offering flexibility for global users, and includes features for historical trend analysis using market chart data. All alerts are stored persistently in local configuration files to ensure they remain active across agent restarts.

Installation

To integrate this skill into your environment, use the OpenClaw command-line interface. Run the following command in your terminal:

clawhub install openclaw/skills/skills/sa9saq/price-monitor

Ensure that you have curl and jq installed on your host system to facilitate the API requests and JSON data formatting required for seamless operation.

Use Cases

• Market Surveillance: Quickly check the current value of your portfolio assets or top-market-cap coins without opening a browser.
• Automated Trading Assistance: Set up triggers to notify you immediately when a coin hits a specific "buy" or "sell" threshold, ensuring you never miss a market move.
• Trend Research: Request 7-day historical charts to analyze volatility before making informed decisions.
• Global Finance: Monitor assets in non-USD currencies like JPY, EUR, or GBP to suit your local financial reporting needs.

Example Prompts

1. "What is the current price and 24-hour percentage change for Bitcoin and Ethereum?"
2. "Set an alert to notify me if Solana drops below $150 USD."
3. "Show me the last 7 days of price movement for Cardano in a table format."

Tips & Limitations

• Rate Limiting: Note that the free tier of the CoinGecko API is limited to approximately 30 requests per minute. The skill manages this by caching responses for 60 seconds; avoid frequent, rapid-fire queries to prevent temporary IP bans.
• Data Freshness: Market data from free-tier APIs may experience a 1–3 minute latency. Always treat the displayed data as a reference rather than an execution-grade price feed.
• Input Sanitization: Always provide coin IDs using standard alphanumeric strings or hyphens to ensure the API mapping functions correctly.
• Alert Management: Since alerts are saved to ~/.openclaw/price-alerts.json, you can manually back up or edit this file if you need to manage a large volume of complex price triggers.
