 For simplicity, you can directly ask for the vector of floats and disgard the extra metadata with `api.Embeddings.GetEmbeddingsAsync("test text here")`

+### Moderation
+The Moderation API is accessed via `OpenAIAPI.Moderation`:
+
+```csharp
+async Task<ModerationResult> CreateEmbeddingAsync(ModerationRequest request);
+
+// for example
+var result = await api.Moderation.CallModerationAsync(new ModerationRequest("A test text for moderating", Model.TextModerationLatest));
+// or
+var result = await api.Moderation.CallModerationAsync("A test text for moderating");
+
+Console.WriteLine(result.results[0].MainContentFlag);
+```
+
+The results are in `.results[0]` and have nice helper methods like `FlaggedCategories` and `MainContentFlag`.

 ### Files (for fine-tuning)
 The Files API endpoint is accessed via `OpenAIAPI.Files`:
