# Guide Titles, Descriptions, and Artwork

Apply the [🏷️ Guide Titles, Descriptions, and Artwork](/quick-start/explainer-videos/set-titles-and-images.md) recipe in C# to steer naming and visuals for `outputType: "video"` responses.

```csharp
// Requires .NET 7+ for raw string literals.
using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;

var token = Environment.GetEnvironmentVariable("AUTOCONTENT_TOKEN") ?? "YOUR_API_TOKEN";
var endpoint = "https://api.autocontentapi.com/content/Create";

var payloadJson = """
{
  "outputType": "video",
  "resources": [
    { "type": "youtube", "content": "https://www.youtube.com/watch?v=dQw4w9WgXcQ" }
  ],
  "text": "Summarize this tutorial into a 90-second explainer for enterprise buyers",
  "title": "Modern Identity Security in 90 Seconds",
  "titlePrompt": "Keep it punchy and benefits-forward",
  "descriptionPrompt": "Include a one-sentence CTA to download the whitepaper",
  "thumbnailImagePrompt": "Flat illustration of a secure cloud, teal and navy palette, minimal text",
  "introImagePrompt": "Logo lockup on gradient with subtle motion trails"
}
""";

using var client = new HttpClient();
using var request = new HttpRequestMessage(HttpMethod.Post, endpoint)
{
    Content = new StringContent(payloadJson, Encoding.UTF8, "application/json")
};
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", token);
request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

var response = await client.SendAsync(request);
var body = await response.Content.ReadAsStringAsync();

if (!response.IsSuccessStatusCode)
{
    Console.Error.WriteLine("Request failed: " + (int)response.StatusCode + " " + response.ReasonPhrase);
    Console.Error.WriteLine(body);
    Environment.Exit(1);
}

Console.WriteLine("Request accepted:");
Console.WriteLine(body);
```

Set `YOUR_API_TOKEN` (or `AUTOCONTENT_TOKEN`) before running.
