In this specific case, we will use a generic \"AI Agent\" node to illustrate that it could use other models from different data providers.\n\n### Enhanced Weather Forecasting\n\nIn this small example, it's easy to demonstrate how to obtain weather forecast results from the Open-Meteo site to accurately display the upcoming days.\n\nThis can be used to plan travel decisions, for example.\n\n## What this workflow does\n\n1. We will make an HTTP request to find out the geographic coordinates of a city.\n2. Then, we will make other HTTP requests to discover the weather for the upcoming days.\n\nIn this workshop, we demonstrate that the AI will be able to determine which tool to call first\u2014it will first call the geolocation tool and then the weather forecast tool. All of this within a single client conversation call.\n\n\n## Setup\n\nInsert an OpenAI Key and activate the workflow.\n\nby Davi Saranszky Mesquita\nhttps://www.linkedin.com/in/mesquitadavi/"}, "typeVersion": 1}, {"id": "3cfeea52-a310-4101-8377-0f393bf54c8d", "name": "Sticky Note1", "type": "n8n-nodes-base.stickyNote", "position": [60, -440], "parameters": {"width": 340, "height": 220, "content": "## Create an Hosted Web Chat\n\n### And setup the trigger!\n\nExample: https://website/webhook/4a4..../chat"}, "typeVersion": 1}, {"id": "55713ffc-da61-4594-99f4-ca6b448cbee2", "name": "Generic AI Tool Agent", "type": "@n8n/n8n-nodes-langchain.agent", "position": [440, -300], "parameters": {"options": {}}, "typeVersion": 1.7}, {"id": "7f608ddc-87bb-4e54-84a8-4db6b7f95011", "name": "Chat Memory Buffer", "type": "@n8n/n8n-nodes-langchain.memoryBufferWindow", "position": [200, -60], "parameters": {}, "typeVersion": 1.3}, {"id": "77f82443-1efe-47d3-92ec-aa193853c8a5", "name": "Sticky Note2", "type": "n8n-nodes-base.stickyNote", "position": [320, 0], "parameters": {"width": 260, "content": "-\n\n\n## Setup OpenAI Key"}, "typeVersion": 1}, {"id": "ed37ea94-3cff-47cb-bf45-bce620b0f056", "name": "Sticky Note5", "type": "n8n-nodes-base.stickyNote", "position": [780, 60], "parameters": {"color": 4, "width": 280, "height": 360, "content": "### Open Meteo SPEC -
