Acceptable parameters:

=over 4

=item  APIKEY

The API key used for authentication with the service.

=item  MARKUP_ONLY

If set to true, a faster variant of the API call is made that only returns
the markup element. Default is to provide everything (images, related articles,
markup and tags).

If supplied the value is prepended to this module's identification string

Otherwise just Net::Zemanta's user agent string will be sent.
