Let them try it. Cap the envelope.

Pre-set the envelope. End the key.

1. 01
   Pre-set the operating envelope

   Required request ceiling, plus optional spend, token, expiry, and IP controls. Speak in controls, not anecdotes.

2. 02
   The walkthrough works, then stops

   The prospect uses a Till key, not an unconstrained provider credential. A ceiling is the operation limit for that demo, not a rate limit and not a substitute for provider billing alerts.

3. 03
   When the demo ends, revoke the key

   Convert interest by requesting Pro beta access, not by pointing at self-serve checkout. Public signup is closed.

4. 04
   Pro: $59/month, 25 scoped keys, 25,000 monthly activations

   Those are plan limits. Provider inference is billed by the provider. Till charges a platform subscription and is not a zero-knowledge vault, prompt firewall, or compliance certification.
