API Simulator (Frontend Only)



        

          
How to use this simulator

          
    
            
  • Opening /api/... in browser directly returns 404 here, because this project is static frontend (no backend routes).
    • 
            
  • Copy URL helps learners inspect and understand endpoint structure (path params + query params).
    • 
            
  • Copy cURL helps learners test the same request in terminal/Postman later when a real backend exists.
    •
