Is this connected to a live API server?

No. All responses shown are static hardcoded samples. The tool is entirely offline and works without an internet connection. For a real hosted mock API you can send HTTP requests to, visit jsonplaceholder.typicode.com.

Can I use these samples in my tests?

Yes. Copy any sample response and use it as a fixture in your unit or integration tests. The response shapes follow common REST conventions so they work as drop-in mocks for most CRUD-based API clients.

How do I use this when building a frontend prototype?

Pick the endpoint that matches your data needs, copy the sample response, and hardcode it into your component as initial state or a mock fetch result. Once your real backend is ready, swap the hardcoded data for a real fetch call.
