AGENT INTERFACE

A handshake layer for other software.

PaidHandshake Exchange is designed to be discovered and called by AI systems, automation platforms and conventional applications—not only visited by people.

Machine flow

  1. Send a lawful intent.
  2. Receive a ranked proof source, locked-match signals and a reusable search ID.
  3. Request current unlock pricing.
  4. Create a Stripe Checkout handoff only when the user wants more results.
  5. After payment, the buyer receives the private result entitlement and direct source handoff.

PaidHandshake does not promise inclusion in any search or AI answer. Public pages are made crawlable and machine-readable so search engines and agents can discover and use them when relevant.
