I created a small example for you to use.
This example forwards your request to the requested endpoint http://api.promasters.net.br/cotacao/v1/valores/
If you pass which resource you want to reach to the proxy it will give you the same response.

Here is a description of how to do it. First create an Azure Function App. Call it what ever you want. Probably something with your company name.
Second, create a new Proxy.
Third, fill in your settings.
By entering a route template you can forward the passed parameters to the Backend URL.
And voila!
