Analyze crypto markets with interactive graphs using CoinGecko and C1 by Thesys

This n8n template can answer questions about real-time prices, market moves, trending coins, and token details with interactive UI in real time (cards, charts, buttons) instead of plain text using C1 by Thesys. Data is fetched through the CoinGecko Free MCP tool.

Check out a working demo of this template here.

What this workflow does A user sends a message in the n8n Chat UI (public chat trigger). The AI Agent interprets the request. The agent calls CoinGecko Free MCP to fetch market data (prices, coins, trending, etc.). The model responds through C1 by Thesys with a streaming, UI answer.

Example prompts you can try right away Copy/paste any of these into the chat:

“What’s the current price of Bitcoin and Ethereum?” “Give me today’s market summary: total market cap, BTC dominance, top gainers/losers.” “Compare ETH vs SOL over 30 days with a chart.”
