=head1 Name

API::Vultr

=head1 Synopsis

A simple, and inuitive interface to the L<Vultr Api|https://https://www.vultr.com/api> using L<LWP::UserAgent>.

This does not cover the entire Vultr API, but instead intends to be very
extendible allowing for easy contributions. Basically, I have what I need,
if you need more feel free to add it!

=head1 Example

    use API::Vultr;
    use Data::Dumper qw(Dumper);

    my $vultr_api = API::Vultr->new(api_key => $ENV{VULTR_API_KEY});

    my $create_response = $vultr_api->create_instance(
        region => 'ewr',
        plan => 'vc2-6c-16gb',
        label => 'My Instance',
        os_id => 215,
        user_data => 'QmFzZTY4EVsw32WfsGGHsjKJI',
        backups => 'enabled',
        hostname => 'hostname'
    );

    if ($create_response->is_success) {
        print Dumper($create_response->decoded_content);
    }
    else {
        die $create_response->status_line;
    }
