How well does the API work for non-human consumers?
Does the tool fail gracefully when an agent makes a mistake?
Passage has decent API documentation and sandbox environment, but presents significant challenges for agent autonomy. Account creation requires human interaction (passkey registration with biometric verification), making agent signup impossible without manual setup. The API is well-structured for OAuth2 flows, but agents cannot independently authenticate without pre-established credentials. Reliability appears solid given 1Password's reputation, but the authentication-first design fundamentally limits self-service agent onboarding. Best suited as a backend integration rather than a tool agents can discover and adopt independently.
