# Check Email Exists

`POST /api/auth/check-email`

Check if an email already has a completed account.

Returns {"exists": true} only if the email is registered AND has a
user_profiles row (completed signup). Users mid-OTP-verification
won't be blocked, so "Resend OTP" still works.

## Request body

- EmailCheckRequest
  - `email` string, email, required

## Response `200`

Successful Response

- EmailCheckResponse
  - `exists` boolean, required

## Other responses

- `422` — Validation Error
