AI CoinMarketCap Agent for Live Crypto Prices (n8n)

Get Live Crypto Prices & Rankings in n8n—Powered by GPT‑4o + CoinMarketCap

This AI CoinMarketCap Agent for Live Crypto Prices (n8n) pulls real-time cryptocurrency data—prices, market rankings, metadata, and global stats—using the CoinMarketCap API and GPT‑4o. It’s a modular, tool-routing agent that helps crypto analysts, traders, and developers answer questions accurately inside your n8n automation workflows.

What this workflow does

Designed as part of a broader CoinMarketCap multi-agent system, the agent can run standalone or be triggered by a supervisor AI agent for multi-agent orchestration. When you ask a crypto question, the agent intelligently selects the right CoinMarketCap tool from the following:

• Crypto Map – find CoinMarketCap IDs and active coins
• Crypto Info – retrieve metadata, whitepapers, and social links
• Crypto Listings – get ranked coins by market cap (e.g., top 100)
• CoinMarketCap Price – fetch live price, volume, and supply
• Global Metrics – total market cap, BTC dominance, and circulating supply-related stats
• Price Conversion – convert between crypto and fiat

Use cases

• Automate answers like: “What’s the live price and volume for BTC, ETH, or SOL?”
• Fetch token details on demand: logos, whitepapers, and website/social links
• Run market watch workflows: top 100 listings by market cap or volume
• Convert user-entered amounts (fiat ↔ crypto) without leaving n8n
• Support analysis by getting CoinMarketCap IDs for tokens (e.g., PEPE) before further lookups
