                                        What types of API responses can this tool generate?                                    
                                    

                                        Generate REST API responses, GraphQL schemas, webhook payloads, and custom JSON structures. Includes templates for e-commerce, social media, IoT, and financial data with realistic field values and nested structures.                                    

                                

                                                                

                                    
                                        How do I create custom mock API responses?                                    
                                    

                                        Select a template or start from scratch, configure your data structure with field types and nesting levels, then generate instant mock data. Adjust array sizes, data types, and customize field names to match your API specification.                                    

                                

                                                                

                                    
                                        Can I use the generated mock data in my application?                                    
                                    

                                        Yes! All generated mock data is ready for immediate use in your development environment. Export as JSON files or copy directly to your clipboard. Works with any framework or testing tool that accepts JSON data.                                    

                                

                                                                

                                    
                                        What are the limitations on data generation?                                    
                                    

                                        Generate up to 1000 items per array and nest structures up to 10 levels deep. All processing happens in your browser for privacy and speed. Larger datasets may affect browser performance.                                    

                                

                                                                

                                    
                                        Can I save and reuse my custom templates?                                    
                                    

                                        Export your custom schemas as JSON templates for future use. Import previously saved templates or share them with your team. The tool remembers your last configuration during the session.
