Integrating AI with Open-Meteo API for enhanced weather forecasting
Needs changesNeeds changes. This template uses 2 thing(s) that n8n 3.0 removes: AI Agent v1 (old agent modes), HTTP Request Tool (legacy). 2 breaking item(s) found. Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 6 nodes and runs when a chat message arrives. Along the way it connects OpenAI Chat Model and HTTP Request. It also calls api.open-meteo.com over HTTP.
How it runs
Trigger: When a chat message arrives.
- Generic AI Tool Agent (AI Agent): runs an AI agent, with model: OpenAI Chat Model; 2 tools (A tool for inputting the city and obtaining geolocation, A tool to get the weather forecast based on geolocation); memory: Chat Memory Buffer
Services it uses
HTTP calls to: api.open-meteo.com
Before you upgrade to n8n 3.0
2 things in this workflow are removed in n8n 3.0. Fix them before you upgrade:
- AI Agent v1 (old agent modes) in Generic AI Tool Agent (v1.7): replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
- HTTP Request Tool (legacy) in A tool to get the weather forecast based on geolocation, A tool for inputting the city and obtaining geolocation: replace with HTTP Request node connected to the AI Agent's Tool input.
| Removed in 3.0 | Replace with |
|---|---|
| AI Agent v1 (old agent modes) Generic AI Tool Agent (v1.7) | Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent. |
| HTTP Request Tool (legacy) A tool to get the weather forecast based on geolocation, A tool for inputting the city and obtaining geolocation | HTTP Request node connected to the AI Agent's Tool input |

Use case Workshop We are using this workflow in our workshops to teach how to use Tools a.k.a functions with artificial intelligence. In this specific case, we will use a generic "AI Agent" node to illustrate that it could use other models from different data…
