API Keys

Online reputation checks are optional — if no keys are set, those steps simply report no results. To enable them:

1. Get a Google Safe Browsing API key from Google Cloud Console
2. Get a VirusTotal API key from virustotal.com
3. Open links_scanne.sh and replace the two placeholder values at the top of the file:

GOOGLE_API_KEY="YOUR_GOOGLE_API_KEY_HERE"
VIRUSTOTAL_API_KEY="YOUR_VIRUSTOTAL_API_KEY_HERE"

Important: Never commit real API keys to GitHub.
