# Image Similarity Search API

A FastAPI application for image similarity search using CLIP embeddings and Qdrant vector database.

## Features

- Upload images and store their vector embeddings
- Search for similar images using an uploaded image or base64 encoded image
- Secure API with API key authentication
- Well-organized, modular codebase following OOP principles

## Installation

1. Clone this repository
2. Install dependencies:

```bash
pip install -r requirements.txt
```

3. Set up environment variables (optional, defaults are provided):

```bash
export QDRANT_URL="your-qdrant-url"
export QDRANT_API_KEY="your-qdrant-api-key"
export COLLECTION_NAME="your-collection-name"
export API_KEY="your-api-key"
export PORT=8000
export ENVIRONMENT="production"  # Or "development" for debug mode with auto-reload
```

## Usage

Run the application:

```bash
python app.py
```

The API will be available at http://localhost:8000 (or the port specified in environment variables).

### API Documentation

Once running, API documentation is available at:
- Swagger UI: http://localhost:8000/docs
- ReDoc: http://localhost:8000/redoc

## API Endpoints

- `POST /add-image/`: Add an image to the database
- `POST /add-images-from-folder/`: Add all images from a folder to the database
- `POST /search-by-image/`: Search for similar images using an uploaded image
- `POST /search-by-image-scan/`: Search for similar images using a base64 encoded image
- `GET /collections`: List all collections in the database
- `GET /health`: Health check endpoint
