Example Output

Under openapi 3.0.0, the paths section defines a get request at slash users that returns a list of user objects. It includes query parameters for page and limit, both defined as integers with defaults. The response schema returns an array of objects containing id, name, and email fields. Bearer token security is applied globally.
