Frequently Asked Questions
How do I use the mock API endpoints?
Simply copy the endpoint URL and use it in your application. The API supports GET, POST, PUT, PATCH, and DELETE methods. All endpoints are CORS-enabled, so you can use them from any frontend application.
What is the "seed" parameter?
The seed parameter ensures deterministic data generation. Using the same seed will always return the same data, which is useful for testing and sharing consistent API responses with your team.
How does the Custom API Builder work?
The Custom API Builder lets you define your own data schema with 100+ field types. Build your schema using the visual editor or JSON, then generate data instantly. You get a shareable URL that returns your custom data format.
What field types are available?
We offer 100+ field types across categories: Person (name, email, phone), Internet (URL, IP, password), Commerce (product, price), Location (address, city), Date/Time, Finance (credit card, IBAN), Text (lorem ipsum), Numbers, IDs (UUID, ObjectId), and more.
Is the API rate limited?
The mock API is designed for development and testing purposes. While there are no strict rate limits, please use it responsibly. For production applications, we recommend setting up your own mock server.
Do POST/PUT/DELETE actually save data?
No, the API is stateless. POST requests will echo back your data with a generated ID, PUT/PATCH will merge with the generated data, and DELETE will return a success message. This makes it perfect for testing frontend CRUD operations without affecting any real database.
