=head2 Return details
Each function returns a HASH ref, with a key called 'results', and another key, called 'url'.
The 'url' key contains a string, which is the URL for the retrieved content.
The 'results' key contains another HASH ref with the keys 'etag', 'items' and 'kind'.
From the 'results' key, only the 'items' are relevant to us. This key contains an ARRAY ref,
with a HASH ref for each result. An example of the item array's content are shown below.
