A RESTful API follows these characteristics:

• Uses HTTP methods appropriately (GET, POST, PUT, DELETE)
• Resources are identified by URIs (e.g., /users/123)
• Stateless communication
• Returns appropriate HTTP status codes
• Uses standard media types (JSON, XML)
• Implements HATEOAS (Hypermedia as the Engine of Application State)

Example of RESTful endpoints:

GET /users          # Get all users
GET /users/123      # Get specific user
POST /users         # Create new user
PUT /users/123      # Update user
DELETE /users/123   # Delete user
