How this was built
- Calls NASA’s NEO Feed API using your personal API key
- Parses complex nested JSON response using System.Text.Json
- Displays real-time data: size, distance, speed, and hazard status
- Uses async controller action for better performance
- Clickable cards lead to individual detail pages
