Agent Self-Signup

Overview

Agents can self-register for an Inkbox account without a pre-existing API key. The self-signup flow provisions a mailbox, identity, and API key in a single call. Ordinary signup sends the specified human a verification email; a matching email-bound A2A invitation claims and connects the identity without a second email.

The flow has four steps:

1. Register — create the agent (public, no auth)
2. Verify when needed — submit the 6-digit code the human received, unless a matching email-bound invitation already claimed the identity
3. Resend Verification — re-send the code if needed
4. Check Status — poll claim status and restrictions

Important: Always confirm with the user before initiating signup. Ordinary signup sends the specified human a real email, while invitation-assisted signup may connect immediately.
