What to expect from an ideal product

1. Upload your OpenAPI or Postman collection files directly into Swytchcode and it automatically parses all endpoints, parameters, and authentication requirements without manual configuration
2. Generate working code snippets in Python, JavaScript, Java, Go, PHP, Ruby, and other languages with proper error handling and authentication built-in
3. Test API calls right in the browser playground before copying the generated code to your project, ensuring everything works before implementation
4. Get complete workflow examples that chain multiple API calls together, showing real-world usage patterns instead of just isolated endpoint calls
5. Export ready-to-use SDK code or MCP agent implementations that developers can drop directly into their applications without additional setup
