    This consists of three parts:

    1. If the URL looks suspiciously like an archive, send a HEAD first to
       check the Content-Type is HTML or Simple API, to avoid downloading a
       large file. Raise `_NotHTTP` if the content type cannot be determined, or
       `_NotAPIContent` if it is not HTML or a Simple API.
    2. Actually perform the request. Raise HTTP exceptions on network failures.
    3. Check the Content-Type header to make sure we got a Simple API response,
       and raise `_NotAPIContent` otherwise.
