## Set up steps
1. **Google Cloud Project and Vertex AI API**:
- Create a Google Cloud project.
- Enable the Vertex AI API for your project.
2. **Google AI API Key**:
- Obtain a Google AI API key from Google AI Studio.
3. **Groq AI API Key**:
- Obtain a Groq AI API key from Groq.
3. **Pinecone Account**:
- Create a free account on the Pinecone website.
- Obtain your API key from your Pinecone dashboard.
- Create an index named `seanrag` or any other name in your Pinecone project.
4. **Google Drive**:
- Create a dedicated folder in your Google Drive to store company documents.
5. **Credentials in n8n**:
- Configure the following credentials in your n8n environment:
- Google Drive OAuth2
- Google Gemini (PaLM) API (using your Google AI API key)
- Pinecone API (using your Pinecone API key)
6. **Import the Workflow**:
- Import this workflow into your n8n instance.
7. **Configure the Workflow**:
- Update both Google Drive Trigger nodes to watch the specific folder you created in Google Drive.
- Configure the Pinecone Vector Store nodes to use your `company-files` index.
8. **Optional**
- Set up NocoDB and create a table with the same fields. Map the fields exactly or as preferred.
ConversationHistory - user,email,ai,sessionid,date,datetime
- Remember to map the table name and fields according to your customizations.

This endpoint api allows you to chat with the ai agent.
The ai agent input router will determine if the nature of question best answered with RAG or SQL agent. Then it invokes the workflow rag or workflow db agent accordingly. When the answer comes back , there is an AI agent output guardrail that uses the answer and validates before responding.
### How to integrate
1. Connect your frontend interface to this api below. You may change the base endpoint to `webhook` or `webhook-test` depending on your environment.
You can also change the based the endpoint 'https://n8n.io' to your own hosted domain like 'https://mycustomdomain.io/'
```
curl -X POST 'https://n8n.jom.lol/webhook-test/radar-rag' -H 'Content-Type: application/json' -d '{
\"chatInput\": \"i wanna write agentic ai code, which strategic direction \"
}'
curl -X POST 'https://n8n.jom.lol/webhook-test/radar-rag' -H 'Content-Type: application/json' -d '{
\"chatInput\": \"is backstage used by company2 \"
}'
```
2. You will see a sample output response:
```
[
{
\"output\": \"Based on the researched answer provided, the tools that are considered strategic directions but are not used by company3 are:\n\n* Automatically generate Backstage entity descriptors (technique)\n* Arm in the cloud (platform)\n* Azure OpenAI Service (platform)\n* Infrastructure orchestration platforms (platform)\n* Rancher Desktop (platform)\n* Conan (tool)\n* Karpenter (tool)\n* GitHub Copilot (tool)\n* Renovate (tool)\n* Velero (tool)\n* Continue (tool)\n* LLaVA (tool)\n* Ollama (tool)\n* DataComPy (language and framework)\n* Ray (language and framework)\n* Concrete ML (language and framework)\n* Crux (language and framework)\n* Electric (language and framework)\n* Mojo (language and framework)\n\nThese tools and technologies are considered strategically important for the organization, but for various reasons, they haven't been adopted by company3 yet.\"

This setup is important to ensure that the tech radar google sheets are stored and transformed into the mysql database so that the sql ai agent can interact with it.
For the RAG ai agent to interact with vector database we need ensure we have converted from gsheet into google docs and subsequently into vector database.

Make sure the search query uses alot wildcard and convert lowecase.
You must not return any technical information but rather the result of the sql query execution.
Please check the schema of database , schema of table ,column names schema before running actual sql query.
Fetch all data to analyse it for response if needed.
