Which page to return, counting from 1. Defaults to page 1.

Leaving this off does not return every row — every list on this API
is paged. See per_page for the size, and read
meta.pagination.perPage back rather than assuming it.

How many rows you want per page, from 1 to 100.

Omitted, it falls back to a server-configured default (25 today).
Read the size actually applied from meta.pagination.perPage rather
than assuming this number — it is configuration, not contract, and it
has already changed once.

The number of rows in data is therefore the size of the PAGE, never
of the list. meta.pagination.total is the size of the whole list, so
a single call with per_page=1 sizes a list before you fetch it, and
hasMore says whether more remain.
