## Usage

```ts
const response = await fetch("/api/patients", {
  method: "POST",
  headers: {
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    name: "Example Patient"
  })
});

if (!response.ok) {
  throw new Error(`Request failed: ${response.status}`);
}

const patient = await response.json();
console.log(patient);
```

## AI Coding Instructions

- Define HTTP endpoints in ASP.NET Core controllers that inherit from `ControllerBase` or `Controller`.
- Use attribute routing such as `[Route]`, `[HttpGet]`, and `[HttpPost]` to map controller actions.
- Return MVC action results such as `Ok`, `Created`, `BadRequest`, and `NotFound` from controller actions.
- Keep JavaScript clients aligned with controller route paths, HTTP methods, request bodies, and response formats.
