# Welcome

Welcome to the **API Key Management and PDF Processing System** API documentation. This API allows administrators to manage users and their API keys, and authenticated users to upload and process PDF files. 

The system integrates with MongoDB for data storage, Google Cloud Storage (GCS) for file storage, and utilizes OpenAI and ZeroX for processing PDFs.
