Data Collection Schedule

The backend automatically scrapes data from various sources at the following intervals:

• Weather Data: Every 30 minutes
• Avalanche Reports: Twice daily (08:30 and 17:30)
• Ski Resort Infrastructure (Lifts & Slopes): Every hour

Manual scraping can also be triggered via API endpoints.

API Endpoints

The backend provides a rich set of REST APIs to access the collected data. Here are some of the key endpoints:

• GET /api/resorts/with-avalanche - All resorts with avalanche data
• GET /api/skiresort/lifts - All lift statuses
• GET /api/weather - Weather data
• POST /api/recommendation/skiresort - Get recommendations
• GET /api/health - Health check
