# Resend signup OTP

`POST /signup/screener/resend_otp`

## Request

- Base URL: `https://api.stablesea.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.stablesea.com/signup/screener/resend_otp`
- Auth: none declared

Re-issues the OTP for an in-flight screener session by re-running registration step 1 for the supplied business email, minting a fresh OTP and re-delivering the email. Acknowledges the same way for an address that already has an account, which is then emailed a sign-in prompt rather than a code: this endpoint never reveals whether an address is registered. While GET /identity/bot_challenge_settings answers required=true, a request without a valid challenge_token is refused (bot_challenge_required / bot_challenge_failed) before any email.

## Request body

- SignupResendOTPInput
  - `challenge_token` string: The bot-challenge token the widget issued for the resend_otp action. Required while GET /identity/bot_challenge_settings answers required=true; ignored otherwise. Single use.
  - `email` string
  - `otp_session_id` string

## Response `200`

OK
