----

The _public_ constructor of `HttpClientWrapper` uses `HttpClient` as a parameter, so it is exposed to consumers and therefore belongs to the API. Note that `HttpGet` and `HttpEntity` are used in the signature of a _private_ method, and so they don't count towards making HttpClient an API dependency.
