AI Weather Forecast Chatbot with Open-Meteo API Tools

This n8n workflow demonstrates how to give an AI agent real-world tools it can call on its own. Ask about the weather in any city through a simple chat interface, and the agent decides for itself to first look up the city's geographic coordinates and then query the free Open-Meteo API to fetch an accurate multi-day forecast, presenting the answer conversationally. Built as an educational template for anyone learning tool-calling patterns in n8n, it's also directly useful for travel planning, event scheduling, or any app that needs a natural-language weather assistant without paying for a commercial weather API.
