# Nodeflux Cloud Client Library for Python

This repository is a Python client library for Nodeflux Cloud Analytics. It implements the APIs defined in [nodefluxapis](https://gitlab.com/nodefluxio/nodefluxapis).

## Installation

```
pip install nodeflux-cloud
```

## Example

```python
# image_analytic.py

from nodeflux.cloud.clients import ImageAnalyticClient
from nodeflux.cloud.requests import ImageAnalyticRequest, AnalyticTypes

client = ImageAnalyticClient()

with open('some-image.jpg', 'rb') as image_file:
    image_content = image_file.read()

requests = [
    ImageAnalyticRequest(
        image_content,
        [
            AnalyticTypes.FACE_DETECTION,
            AnalyticTypes.FACE_DEMOGRAPHY,
            AnalyticTypes.FACE_RECOGNITION,
        ],
    )
]

response = client.batch_image_analytic(requests)

print(response)
```

Setup your credentials and run the example:

```bash
$ export NODEFLUX_ACCESS_KEY={YOUR_ACCESS_KEY}
$ export NODEFLUX_SECRET_KEY={YOUR_SECRET_KEY}
$ python image_analytic.py
responses {
  face_detections {
    bounding_box {
