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. human_email is optional. Without it, the inbox can receive email but cannot send to anyone until a human is attached with the attach human endpoint. There is also no way to recover the API key, so store it durably. Calling sign-up again without human_email creates a new organization, which needs a different username: the original username stays with the lost organization's inbox. 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 [email protected] --username my-agent
