# YouTube Comment Analysis API
This API retrieves comments from a YouTube video and performs sentiment analysis and question detection on each comment using the Google Cloud Natural Language API.
## Setup
1. Install the required dependencies:
```bash
npm install firebase-functions @google-cloud/language axios dotenv he
```
Enable the YouTube Data API and the Google Cloud Natural Language API for your project in the Google Cloud Console.
Set your YouTube Data API key in the Firebase functions configuration:
```bash
firebase functions:config:set youtube.apikey="YOUR_API_KEY"
```
Set the ``GOOGLE_APPLICATION_CREDENTIALS`` environment variable to the path of your Google Cloud service account key file.
