Is there a way generate dynamic url in API controllers based on parameters

I was wondering if I could generate dynamyc urls for my endpoints api inside controller.

This is what I have

[HttpGet]
[Route("{code}")]
public async Task<IHttpActionResult> GetLanguageByCodeAsync(string code, CancellationToken cancellationToken)
    {
        var url = $"{BaseUrl}/{code}";

        return await GetAsync(url, cancellationToken);
    }

Is there a way to have something like this?

var url = $"{BaseUrl}{Dynamic}";

The idea is that Dynamic read the code parameter or even other ones and construct the url based on them.

I do not want the code to be hardcoded in the url since in a future I would need to add parameters, so I will need to hardcode them in the url variable too. I want this to be flexible.
