# API Reference

The API is divided in two logical blocks:

1. High-level API, abstracting all the complexity of a RAG (Retrieval Augmented Generation) pipeline implementation:
    - Ingestion of documents: internally managing document parsing, splitting, metadata extraction,
      embedding generation and storage.
    - Chat & Completions using context from ingested documents: abstracting the retrieval of context, the prompt
      engineering and the response generation.

2. Low-level API, allowing advanced users to implement their own complex pipelines:
    - Embeddings generation: based on a piece of text.
    - Contextual chunks retrieval: given a query, returns the most relevant chunks of text from the ingested
      documents.
