• GET /api/formula1 - Get Formula 1 season data
• GET /api/formula1nextrace - Get next Formula 1 race
• GET /api/weather - Get weather data for a location
• GET /api/crypto - Get cryptocurrency price data
• GET /api/news - Get top news headlines
• GET /api/finance - Get stock market data

API Documentation

The API documentation is available at http://localhost:5173/docs/ and provides:

• Interactive Swagger UI interface
• Detailed API endpoint documentation
• Request/response schemas
