Building a mock API used to mean writing schemas, setting up servers, and maintaining fake data. With SimulAPI, you describe what you need in plain language and get a working REST API in seconds.
Step 1: Create a project
Sign up for a free account and create a new project. Give it a name like "Todo API" or "User Service."
Step 2: Describe your API
In the AI workspace, type something like: "Create a Todo API with tasks that have title, dueDate, and completed. Include GET /tasks and POST /tasks." The AI generates a valid OpenAPI spec and live endpoints.
Step 3: Use your API
Copy your base URL and start making requests. You get realistic JSON responses with no extra configuration. Share the URL with your frontend team or use it in tests.
What's next?
Try adding more endpoints, nested resources, or custom response shapes. SimulAPI supports full REST semantics—GET, POST, PUT, PATCH, and DELETE—so you can prototype any API you need.
