cmc-api-exchange

What This Skill Does

The cmc-api-exchange skill acts as an authoritative interface for the CoinMarketCap Exchange API. It enables OpenClaw to retrieve comprehensive data on centralized exchanges, including metadata, real-time and historical trading volumes, market pair listings, and proof-of-reserves data. This skill is essential for users, developers, and analysts who need to verify exchange liquidity, explore available trading pairs across different platforms like Binance, Kraken, or Coinbase, and integrate professional-grade financial market data directly into their automation workflows.

Installation

To integrate this skill into your OpenClaw environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/bryan-cmc/cmc-api-exchange

Ensure you have an active API key from the CoinMarketCap Pro developer portal. Once installed, the skill will automatically intercept relevant queries regarding exchange data and route them through the secured API headers.

Use Cases

This skill is designed for high-precision financial data retrieval. Key use cases include:

• Liquidity Analysis: Comparing 24-hour trading volumes across multiple exchanges to identify deep-liquidity markets for high-volume orders.
• Asset Discovery: Finding which exchanges support specific cryptocurrency assets by querying market-pair data.
• Risk Management: Checking exchange-reported reserves (proof-of-reserves) to evaluate platform transparency.
• Operational Integration: Automating the lookup of exchange IDs based on human-readable names to facilitate programmatic calls to other CMC endpoints.
• Trading Strategy Development: Pulling historical volume data to analyze market trends and seasonal volatility in exchange activity.

Example Prompts

1. "Can you show me the top 5 exchanges by 24-hour volume and their current liquidity ranking?"
2. "What are all the BTC trading pairs available on Binance, and what is their current volume?"
3. "Look up the exchange metadata and proof-of-reserves for Coinbase using the CMC exchange API."

Tips & Limitations

• Rate Limiting: Always be mindful of your CMC API plan tier. Excessive requests will trigger rate limits.
• ID Mapping: Many endpoints require a specific CMC ID. If you only have the exchange name, always perform a lookup via /v1/exchange/map first.
• Latency: While the data is near-real-time, ensure your network connection is stable to avoid partial data sets during batch requests.
• Authentication: Ensure your API key is stored securely in your environment variables; never hardcode it into custom scripts.
