Being as we are early in the adoption of personal agents the primary users of it are early adaptors who are incredibly flexible and open to new paradigms.

Requiring a human to login and verify an email address after making 5 searches might seem annoying but these early adapters understand tech and if you make it clear in your error message, they will likely understand why this is needed. They will adapt to this new paradigm.

If email verification isn’t enough, step up another verification. Require cell phone number verification. If that still isn’t enough then try credit card verification or a one time verification fee. That is a bit extreme but I want to give you some options.
