For a given API, the base_url and user_agent will almost always be the
same. Use this function to prepare that piece of the request once for easy
reuse.
Arguments
- base_url
- The part of the url that is shared by all calls to the API. In some cases there may be a family of base URLs, from which you will need to choose one. 
- ...
- These dots are for future extensions and must be empty. 
- user_agent
- A string to identify where this request is coming from. It's polite to set the user agent to identify your package, such as "MyPackage (https://mypackage.com)". 
Value
A httr2::request() object.
