# GitHub API chatbot: answers documentation questions using RAG and OpenAI
This workflow enables users to ask questions about the GitHub API in a chat interface and receive accurate, context-aware responses based on the latest OpenAPI specification. It uses a RAG approach: fetching and chunking official documentation, storing embeddings in Pinecone, and generating answers via a GPT-4o-mini-powered agent. Ideal for teams needing instant, reliable API reference without manual search.
## Who it´s for
- Developers working with GitHub API who need quick access to documentation.
- Technical specialists automating API support via chatbots.
- DevRel teams building interactive API reference systems.
- Engineers testing RAG solutions on real OpenAPI specs.
## What the automation does
- On receiving a chat message, triggers a RAG agent to process the query.
- Performs semantic search in Pinecone vector database populated with GitHub’s OpenAPI spec chunks.
- Sends retrieved context to GPT-4o-mini for natural language response generation.
- Maintains conversation history via memory buffer for contextual continuity.
- Allows manual or scheduled updates of documentation from GitHub’s API.
## What´s included
- Ready-to-use n8n workflow with full RAG agent logic.
- Trigger logic: manual execution or on new chat message.
- Integrations with GitHub (API), Pinecone (vector store), and OpenAI (LLM).
- Basic text guide for setup and adaptation.
## Requirements for setup
- n8n instance with workflow execution capability.
- Pinecone account for vector storage.
- OpenAI API key for GPT-4o-mini access.
- Chat interface compatible with n8n (e.g., via webhook).
## Benefits and outcomes
- Instant access to precise GitHub API information without browsing docs.
- Reduced load on technical support through self-service.
- Scalable architecture suitable for enterprise knowledge bases.
- Flexible design adaptable to other OpenAPI specifications.
- Time savings for developers interacting with GitHub API.
