# Submit signup screener

`POST /signup/screener/submit`

Validates the screener payload (business email + business name) and starts an identity registration session. Answers 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.

## Request body

- SignupScreenerSubmitInput
  - `business_name` string
  - `email` string
  - `first_name` string
  - `last_name` string
  - `role` string

## Response `200`

OK

- SignupScreenerSubmitOutput
  - `qualified` boolean

## Other responses

- `default` — Error response.

## Changes

- **2026-08-19** `f0991172edbc` — 1 warning
  - removed the optional property `otp_session_id` from the response with the `200` status
