# Annotation

> Typed SDK access to the Annotation resource — methods and HTTP routes.

## Typed access

`Annotation` operations are reached via `client.Api.Annotation.Supported` on `EksoClient`.

```csharp theme={null}
await client.Api.Annotation.Supported.ListSupportedAsync();
```

For the full set of methods and request/response types, your IDE's auto-completion
is the fastest discovery path. Each method below maps 1-to-1 to an HTTP route in
the [API Reference](/api-reference/introduction).

## Operations

| Method | Route                       | Summary                                                 |
| ------ | --------------------------- | ------------------------------------------------------- |
| `GET`  | `/api/annotation/supported` | Returns the list of supported annotation content types. |
| `POST` | `/api/annotation`           | Creates a new annotation on the specified owner entity. |
