Dynamic API Endpoint Health Monitoring Dashboard Generator

Create a Bash script that continuously monitors multiple API endpoints across different services, generating real-time health status reports and triggering alerts. The script should ping endpoints at configurable intervals, track response times, detect HTTP status code anomalies, and output results to both console and a structured log file. Implement advanced features like exponential backoff for failed requests, webhook notifications for critical failures, and a summary dashboard that can be easily integrated with monitoring platforms.
