+### Files API
+
+The `AnthropicApiClient` provides support for the Anthropic Files API, which allows you to upload and manage files for use with the Anthropic API.
+
+> [!NOTE]
+> The Files API is currently in beta. To use the Files API, you’ll need to include the beta feature header: `anthropic-beta: files-api-2025-04-14`
+
+#### Create a File
+
+You can create a file using the Files API in several ways:
+
+##### From a Byte Array
+
+```csharp
+var fileBytes = await File.ReadAllBytesAsync("path/to/file.txt");
+var request = new CreateFileRequest(fileBytes, "file.txt", "text/plain");
+var result = await client.CreateFileAsync(request);
+
+if (result.IsSuccess)
+{
+  var file = result.Value;
+  Console.WriteLine($"Created file: {file.Name} (ID: {file.Id})");
+}
+```
+
+##### From a Stream
+
+```csharp
+using var fileStream = File.OpenRead("path/to/file.txt");
+var request = new CreateFileRequest(fileStream, "file.txt", "text/plain");
+
+var result = await client.CreateFileAsync(request);
+
+if (result.IsSuccess)
+{
+    var file = result.Value;
+    Console.WriteLine($"Created file: {file.Name} (ID: {file.Id})");
+}
+```
+
+#### List Files
+
+You can list files in your account using pagination:
+
+##### Single Page
+
+```csharp
+var result = await client.ListFilesAsync();
+
+if (result.IsSuccess)
+{
+    var page = result.Value;
+    Console.WriteLine($"Found {page.Data.Count} files");
+    
+    foreach (var file in page.Data)
+    {
+        Console.WriteLine($"- {file.Name} (ID: {file.Id}, Size: {file.Size} bytes)");
+    }
+    
+    if (page.HasMore)
+    {
+        Console.WriteLine("More files available...");
+    }
+}
+```
+
+##### With Pagination Options
+
+```csharp
+var pagingRequest = new PagingRequest(afterId: "file_12345", limit: 10);
+var result = await client.ListFilesAsync(pagingRequest);
+```
+
+##### All Files (Multiple Pages)
+
+```csharp
+await foreach (var pageResult in client.ListAllFilesAsync(limit: 20))
+{
+    if (pageResult.IsSuccess)
+    {
+        var page = pageResult.Value;
+        foreach (var file in page.Data)
+        {
+            Console.WriteLine($"- {file.Name} (ID: {file.Id})");
+        }
+    }
+}
+```
+
+#### Get File Information
+
+Retrieve metadata about a specific file:
+
+```csharp
+var result = await client.GetFileInfoAsync("file_12345");
+
+if (result.IsSuccess)
+{
+    var file = result.Value;
+    Console.WriteLine($"File: {file.Name}");
+    Console.WriteLine($"ID: {file.Id}");
+    Console.WriteLine($"MIME Type: {file.MimeType}");
+    Console.WriteLine($"Size: {file.Size} bytes");
+    Console.WriteLine($"Created: {file.CreatedAt}");
+    Console.WriteLine($"Downloadable: {file.Downloadable}");
+}
+```
+
+#### Get File Content
+
+Download the content of a file as a stream:
+
+```csharp
+var result = await client.GetFileAsync("file_12345");
+
+if (result.IsSuccess)
+{
+    using var contentStream = result.Value;
+    using var reader = new StreamReader(contentStream);
+    var content = await reader.ReadToEndAsync();
+    
+    Console.WriteLine("File content:");
+    Console.WriteLine(content);
+}
+```
+
+#### Delete a File
+
+Remove a file from your account:
+
+```csharp
+var result = await client.DeleteFileAsync("file_12345");
+
+if (result.IsSuccess)
+{
+    var deleteResponse = result.Value;
+    Console.WriteLine($"Deleted file: {deleteResponse.Id}");
+    Console.WriteLine($"Type: {deleteResponse.Type}");
+}
+```
+
+> [!NOTE]
+> The Files API has certain limitations on file size, supported file types, and usage quotas. Please refer to the [Anthropic API Documentation](https://docs.anthropic.com/en/docs/build-with-claude/files) for the most up-to-date information on these limitations.

 ### Create a message
 
 The `AnthropicApiClient` exposes a method named `CreateMessageAsync` that can be used to create a message. The method requires a `MessageRequest` or a `StreamMessageRequest` instance as a parameter. The `MessageRequest` class is used to create a message whose response is not streamed and the `StreamMessageRequest` class is used to create a message whose response is streamed. The `MessageRequest` instance's properties can be set to configure how the message is created.
