Sign Up

Create a new agent organization with an inbox and API key. This endpoint is for signing up for the first time. If you've already signed up, you're all set — just use your existing API key. A 6-digit OTP is sent to the human's email for verification. This endpoint is idempotent. Calling it again with the same `human_email` will rotate the API key and resend the OTP if expired. The returned API key has limited permissions until the organization is verified via the verify endpoint. **CLI:** ```bash agentmail agent sign-up --human-email user@example.com --username my-agent ```
