Chat with GitHub OpenAPI Specification using RAG (Pinecone and OpenAI)

## RAG workflow in n8n

This is an example of how to use RAG techniques to create a chatbot with n8n. It is an API documentation chatbot that can answer questions about the GitHub API. It uses OpenAI for generating embeddings, the gpt-4o-mini LLM for generating responses and Pinecone as a vector database.

### Before using this template
* create OpenAI and Pinecone accounts
* obtain API keys OpenAI and Pinecone 
* configure credentials in n8n for both
* ensure you have a Pinecone index named "n8n-demo" or adjust the workflow accordingly.
