detail.loadingPreview
Leverage AI to dynamically answer questions about Hacker News trends. This workflow allows an AI agent to fetch and process real-time data, providing instant insights into popular posts.
About This Workflow
This n8n workflow empowers an AI agent to interact with Hacker News data. Triggered by a manual chat message, the AI agent can utilize a custom tool to query the Hacker News API. The workflow fetches the top 50 posts, cleans the relevant data such as title, points, URL, creation date, and author, and then formats it for the AI. This creates a seamless experience where you can ask natural language questions about Hacker News and receive precise, data-driven answers, all automated through n8n's powerful integration capabilities with Langchain and OpenAI.
Key Features
- AI-Powered Q&A: Ask complex questions about Hacker News data in natural language.
- Custom Tool Integration: The AI agent can leverage a custom workflow tool to access Hacker News data.
- Real-time Data Fetching: Retrieves up-to-date information from the Hacker News API.
- Data Cleaning and Formatting: Prepares data for the AI for efficient processing.
- OpenAI Integration: Utilizes OpenAI's chat models for intelligent responses.
How To Use
- Set up OpenAI Credentials: Ensure your OpenAI API key is configured in n8n.
- Configure Manual Chat Trigger: The 'On new manual Chat Message' node acts as the initial trigger. You can interact with it directly in n8n.
- AI Agent Setup: The 'AI Agent' node is configured to use the 'OpenAI Chat Model' and is equipped with a custom tool.
- Custom Tool Definition: The 'Custom tool to call the wf below' node defines the 'hn_tool' that the AI agent can call. It points to a sub-workflow that fetches Hacker News data.
- Hacker News Data Fetching: The 'Execute Workflow Trigger' node initiates the sub-workflow, which then uses the 'Hacker News' node to fetch data.
- Data Processing: The 'Clean up data' node extracts and formats the necessary fields from the Hacker News results.
- Stringify Output: The 'Stringify' node prepares the cleaned data in a JSON format for the AI agent.
- Trigger Interaction: Click the 'Chat' button within n8n and ask questions like 'What is the 5th most popular post ever on Hacker News?' to test the workflow.
