4. Step-by-Step Guide
Step 1: Import the Workflow into n8n
Log in to your n8n dashboard. Click Workflows → Import from File. Select the provided JSON file named “CoinMarketCap_AI_Data_Analyst_Agent.json”. The workflow will load, displaying all nodes in the editor.
You should see multiple nodes including the Telegram Trigger, AI Analyst Brain, Memory Buffer, various tool workflows, and Telegram Send Message node.
Common Mistake: Forgetting to import or connect the required sub-agent workflows will cause failures.
Step 2: Configure Telegram Trigger Node
Click on the node labeled “Telegram Input”. Under the credentials section, link your Telegram Bot API credential. This node listens for incoming Telegram messages from users.
Verify by saving and activating the workflow, then sending messages to your Telegram bot to confirm reception.
Expected Outcome: Incoming messages trigger the workflow automatically.
Step 3: Add Session ID with Set Node
The “Adds SessionId” Set node extracts the Telegram chat’s unique ID and assigns it as sessionId. This ensures session continuity and context for conversations.
No configuration needed as it’s templated with {{ $json.message.chat.id }}.
Common Mistake: Not passing a valid chat ID can break session memory.
Step 4: Configure CoinMarketCap AI Data Analyst Agent Node
This is the core node using the LangChain agent type: @n8n/n8n-nodes-langchain.agent. It receives user messages and sessionId to process with its embedded multi-agent AI system.
You don’t need to change system messages unless customizing prompts. The system message explains its tools and capabilities including three sub-agents for crypto, exchanges, and DEX data.
Expected Outcome: The node generates intelligent queries routed to CoinMarketCap API tools.
Step 5: Setup LangChain Memory Buffer
Open the “CoinMarketCap Memory” node. This node maintains conversation state between queries using the memoryBufferWindow type.
Ensure it’s linked to the AI Data Analyst Agent node correctly in the ai_memory input.
This enables the AI to maintain context and give coherent conversational responses.
Step 6: Connect LangChain OpenAI Chat Model
Look for the node called “CoinMarketCap Agent Brain” using type @n8n/n8n-nodes-langchain.lmChatOpenAi. Configure with your OpenAI API credentials.
This node understands natural language prompts and decides how to distribute tasks among agents.
Step 7: Connect Tool Workflow Nodes for Sub-Agent Tools
There are three tool nodes:
- CoinMarketCap Crypto Agent Tool: Linked to a sub-workflow for cryptocurrency market data.
- CoinMarketCap Exchange and Community Agent Tool: Calls sub-workflow handling exchanges and community sentiment.
- CoinMarketCap DEXScan Agent Tool: Accesses decentralized exchange data and trading metrics.
Each is configured to accept message text and sessionId from the AI Data Analyst Agent node’s output for multi-agent querying.
Step 8: Setup Telegram Send Message Node
The node named “Telegram Send Message” automatically sends the AI-generated responses back to the Telegram chat identified by the chat ID from the “Telegram Input” node.
Ensure the Telegram API credential is linked and the text field correctly references {{ $json.output }}.
Expected Outcome: Users receive direct answers in Telegram instantly after querying.
5. Customizations ✏️
Customize the AI System Message
Open the “CoinMarketCap AI Data Analyst Agent” node. Modify the systemMessage parameter to adjust agent instructions, tailoring focus on specific crypto metrics or to include additional CoinMarketCap API endpoints.
Change Telegram Bot Responses Formatting
In the “Telegram Send Message” node, adjust the text field template to include emojis or markdown-styled text for better readability in Telegram chats.
Extend with More Data Sources
Add additional toolWorkflow nodes linked to other CoinMarketCap or external APIs. Map their inputs and outputs similarly to provide enriched crypto insights.
Adjust Memory Buffer Size
In the “CoinMarketCap Memory” node, configure buffer window size to retain more conversational history for complex query follow-ups.
Change Session Handling
In the “Adds SessionId” node, modify how sessionId is derived to support multi-user environments or grouped chats by customizing the assignment logic.
6. Troubleshooting 🔧
Problem: “400 Bad Request” Error from CoinMarketCap APIs
Cause: Invalid or missing required parameters in the query.
Solution: Verify that query inputs like symbol, slug, or id are valid CoinMarketCap values. Use the system message’s validation hints and input field requirements carefully.
Problem: Telegram Messages Not Triggering Workflow
Cause: Telegram webhook not configured correctly or missing bot permission.
