What this workflow does
This AI workflow has 9 nodes and runs when a chat message arrives. Along the way it connects OpenRouter Chat Model and SerpApi (Google Search).
How it runs
Trigger: When a chat message arrives.
- crypto_symbol (Edit Fields (Set)): sets or maps fields
- 1d_Chart (HTTP Request): calls an HTTP API
- Long Term Agent (AI Agent): runs an AI agent, with model: OpenRouter Chat Model; memory: Window Buffer Memory
- 5m_Chart (HTTP Request): calls an HTTP API
- AI Agent: runs an AI agent, with model: OpenRouter Chat Model; 1 tool (SerpAPI); memory: Window Buffer Memory
Services it uses
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 AI Agent (v1.7), Long Term 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.
- SerpApi (Google Search) in SerpAPI: no direct replacement: call the SerpApi REST API with an HTTP Request tool, or use a verified community node.
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
| Removed in 3.0 | Replace with |
|---|---|
| AI Agent v1 (old agent modes) AI Agent (v1.7), Long Term Agent (v1.7) | Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent. |
| SerpApi (Google Search) SerpAPI | No direct replacement: call the SerpApi REST API with an HTTP Request tool, or use a verified community node |
