Install via CLI (Recommended)
clawhub install openclaw/skills/skills/bryan-cmc/cmc-api-cryptoWhat This Skill Does
The cmc-api-crypto skill provides a direct interface to the CoinMarketCap Cryptocurrency API, enabling developers and analysts to integrate professional-grade crypto market data into their workflows via OpenClaw. It serves as a comprehensive wrapper for CoinMarketCap's REST endpoints, abstracting away the boilerplate required to manage headers, authentication, and URL construction. By using this skill, you can programmatically query real-time market data, historical performance metrics, token metadata, and trending asset lists directly from the agent interface.
Installation
To integrate this skill into your environment, use the OpenClaw Command Line Interface (CLI). Ensure you have your authentication token ready from the CoinMarketCap Pro developer portal before proceeding.
Install command:
clawhub install openclaw/skills/skills/bryan-cmc/cmc-api-crypto
Once installed, you must provide your API key to the environment variables to authenticate your requests against the https://pro-api.coinmarketcap.com base URL. Refer to the skill documentation for setting global secrets.
Use Cases
This skill is built for versatility. Use it to:
- Automate price tracking: Get real-time, accurate quotes for any listed cryptocurrency.
- Financial Modeling: Pull historical OHLCV data to perform technical analysis or train predictive models.
- Market Research: Discover trending assets, monitor significant gainers and losers, or query newly listed tokens.
- Asset Metadata: Retrieve logos, project descriptions, website links, and social media handles for specific tokens to populate UI components.
- Categorization: Query tokens within specific industries like DeFi, NFTs, or Layer-2 scaling solutions using the categories endpoint.
Example Prompts
- "CMC API: Get me the current market price and 24-hour volume for Bitcoin and Ethereum."
- "I need to build a price integration; how do I fetch the historical OHLCV data for Solana for the last 30 days?"
- "Show me the top 10 trending coins on CoinMarketCap right now and provide their market cap statistics."
Tips & Limitations
- Respect Rate Limits: The CoinMarketCap API enforces credit limits based on your plan. Monitor your credit usage to avoid service interruptions.
- Error Handling: Always verify the API response format, as CMC updates their schema occasionally.
- Data Freshness: Note that while quote data is near real-time, some metrics may have minor latency based on the specific endpoint version (v1 vs v2). Always use v2 endpoints for the most detailed market data when available.
- Caching: If you are building a high-traffic app, implement local caching to reduce redundant API calls and save on credit consumption.
