# Start a background review of a draft's wording, or find the one already done.

`POST /v1/question-reviews`

## Request

- Base URL: `https://api.50heads.com`
- URL: `https://api.50heads.com/v1/question-reviews`
- Auth: one of:
  - HTTP bearer
  - OAuth 2 (authorization code, authorization URL `https://auth.50heads.com/authorize`, token URL `https://auth.50heads.com/token`; client credentials, token URL `https://auth.50heads.com/token`, scopes: `questions:write`)

Advice only: it never spends and never changes the price. Returns at once with `pending`; ask again (GET) after `retryMs`. The same words are reviewed once a day, so calling it on every save is fine. `skipped` means there was nothing to review, with the reason in `review.skippedReason`. Each suggestion is one change to the draft (`op`) that you apply yourself; a `tidy` suggestion fixes capitals and spacing.

## Other responses

- `400`: The request is not valid; `error.details.validation` lists the fixes.
- `401`: No key or token, or it expired or was revoked.
- `403`: The key or token lacks the scope (`insufficient_scope`), or the action is not allowed.
- `429`: Too many requests; wait for Retry-After.
