UnknownUnknown. This template uses community nodes we can't verify statically. Uses community nodes that can't be verified statically (unverified community packages are off by default in 3.0). Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 14 nodes and runs when a chat message arrives. Along the way it connects OpenAI Chat Model, Google Sheets, OpenAI and Blotato (community). It also calls api.wavespeed.ai over HTTP.
How it runs
Trigger: When a chat message arrives.
- Image Prompt Generator (AI Agent): runs an AI agent, with model: OpenAI Chat Model; output parser: Structured Output Parser
- Split Out: splits a list into separate items
- Caption Generator (OpenAI): uses OpenAI
- Nano Banana (HTTP Request): calls api.wavespeed.ai (POST)
- Merge: merges the data from its input branches
- Wait: waits 60 seconds
- Get Nano Banana Image Result (HTTP Request): calls an HTTP API
- Upload media (Blotato): uses Blotato
- Code: runs custom JavaScript code
- Append row in sheet (Google Sheets): append
…plus 1 more step. See the full node list below.
Services it uses
HTTP calls to: api.wavespeed.ai
Before you upgrade to n8n 3.0
We can't fully verify this one: it relies on 1 community package, and n8n 3.0 turns unverified community packages off by default (N8N_UNVERIFIED_PACKAGES_ENABLED=false).
- Check that @blotato/n8n-nodes-blotato is verified or supports 3.0 (used in Upload media, Post to Instagram).
