Assuming Wolfram|Alpha becomes and remains a significant tool to
get information, I would think WRI will at some point create a
version of Mathematica with a built-in means to query
Wolfram|Alpha directly.

And is undoubtedly one of the main reasons for stating searches
need to be entered manually by a human.

Which is why I would argue your tool complies with the terms of
service. Unless I modify your tool, as designed it only allows
one query at a time which has to be manually entered. And by
restricting the length of the input to be the same as the W|A
query box, in effect, tool is no different whatever from
entering the same query in a box displayed by a web browser. The
only technical difference I see between your tool and entry into
the box displayed by a web browser is that I don't literally
enter the query into the box displayed by the web browser. And
since the actual query sent to W|A is identical in both cases,
there will be no way for WRI to determine what interface I used
to enter the query on my machine. Nor is there any reason for
them to care.

The reality is for ordinary users the terms of service are
essentially meaningless. It is not reasonable to think all or
even most users of W|A will have read the terms of service and
understood them in any significant way. And as you point out
above, if a user creates problems there are ways of dealing with
them regardless of the terms of service. Also, the process for
dealing with an abusive user will not be significantly different
whether the terms of service existed or not.
