Creating an account

Pick a username and a separate @daaymail.com address.

Your login username and your @daaymail.com address are separate — they do not have to match. Recovery email is optional. Do not send name; the API builds it from firstName + lastName.

POST BASE/v1/api/auth/sign/up/email
Content-Type: application/json

{
  "username": "ada",
  "email": "ada@daaymail.com",
  "password": "CorrectHorseBattery1!",
  "confirmPassword": "CorrectHorseBattery1!",
  "firstName": "Ada",
  "lastName": "Example"
}

Or send localPart instead of email (the server builds the full address for you):

{
  "username": "ada",
  "localPart": "ada",
  "password": "CorrectHorseBattery1!",
  "confirmPassword": "CorrectHorseBattery1!",
  "firstName": "Ada",
  "lastName": "Example"
}

The API creates one active mailbox for that address. You get exactly one mailbox per account.

Optional on the same call:

{
  "recoveryEmail": "ada@gmail.com"
}

Without recovery you can sign in with password right away. needsRecoveryEmail stays true until you add recovery later.

Confirm your recovery email (when provided)

POST BASE/v1/api/auth/email/otp/verify
Content-Type: application/json

{
  "email": "ada@daaymail.com",
  "otp": "123456"
}

The code is delivered to the recovery inbox. After a successful verify you are signed in immediately — no separate sign-in needed.
