Example Request
POST /api/convert/json-to-csv
                    X-API-KEY: your_api_key_here
                    Content-Type: application/json

                    {
                      "json": "[{\"name\":\"Alice\",\"age\":30}]"
                    }

📌 Request Format Note All API endpoints accept JSON request bodies. Even when converting CSV data, the CSV content is sent as a string inside a JSON object. This design allows the API to support validation, conversion options, consistent error handling, and future extensibility across all endpoints. As a result, all requests must include: Content-Type: application/json

The API does not accept raw CSV or file uploads at this time.
✅ Example (CSV → JSON)

                "csv": "name,age\nAlice,30\nBob,25"
                }
