String to Endpoint

Hi,

I am writing a route that needs to fetch data from a webpage, the
source webpage depends of the input message. My current
implementation uses "dynamicRouter" but the need of track multiple
calls (I just need to go to fetch the data once) is a big turn off.

Is there a way to make dynamic routes without using "dynamicRouter"?
Or a way to dynamically transform a single value to an endpoint?

Thanks,
