API

The main.py file sets up a FastAPI application (/apy) with multiple sub-applications. Each sub-application endpoint provide a set of services defining one of the main functionalities of the EAK/ZAS CopilotGPT.

Autocomplete (/apy/autocomplete)

Provides an endpoint for questions autocomplete suggestions when typing a message in the search bar. This aims to help users getting a curated answer from the database, avoiding the eventual randomness of the RAG model, while lowering the cost.

Indexing (/api/indexing)

Provides an endpoint for indexing new documents into the database that can be used by the autocomplete or the RAG functionalities.

RAG (/api/rag)

Provides an endpoint for the RAG (Retrieval-Augmented Generation) model to generate responses to user queries based on the indexed documents.

Beside, main.py sets up CORS (Cross-Origin Resource Sharing) middleware to allow the frontend to access the API, a lifespan context manager that initializes the databases with some example data, and a dummy endpoint to check if the API is running.

async main.welcome()

Dummy endpoint for testing the API.

Returns:

A welcome message.
