Key Points

  • The article argues that ZYVV’s decision protocol API differs from calling GPT-4 directly by persisting every step of a user’s decision process as permanent records.
  • Each API call writes structured outcomes (e.g., the chosen “door,” raised doubts, and refined paths) into a collective dataset that compounds over time.
  • The workflow is demonstrated with concrete endpoints: creating a “situation” (/api/v1/doors), recording a selection (/api/v1/choice), and running interrogation to stress-test objections (/api/v1/interrogate).
  • The example shows the API producing multiple decision options (“conventional,” “contrarian,” “alien”) with tailored rationales instead of returning only raw text.
  • The author frames the stored protocol state (situation_id) as a way to keep the conversation grounded in an explicit decision structure rather than a one-off prompt-response.
