Hi,
It is fine to use a cursor as a query parameter.
"A cursor is an opaque base64-encoded string that represents the
next starting position of a query after a fetch operation. The app can
embed the cursor in web pages as HTTP GET or POST parameters."
"It is generally safe to pass a datastore cursor to a client,
such as in a web form, and accept a cursor value from a client. A
client cannot change the cursor value to access results outside of the
original query."
