# Headers

Echo back the HTTP request headers the API received. Useful for debugging what your application (or a proxy in between) is actually sending — user agent, authorization scheme, content negotiation.

## Making Requests

Use `GetHeadersAsync` on the `Utilities` resource.

```csharp
Task<UtilitiesHeadersResponse> GetHeadersAsync(CancellationToken cancellationToken = default)
```

#### Returns

`UtilitiesHeadersResponse` wrapping `IReadOnlyDictionary<string, string>` — header name to value, as received by the API. The `Authorization` value is returned redacted by the API.

## Examples

```csharp
using MarketDataApp;

using var client = await MarketDataClient.CreateAsync();

var headers = await client.Utilities.GetHeadersAsync();
foreach (var (name, value) in headers.Values)
{
    Console.WriteLine($"{name}: {value}");
}
```
