      summary: Submit a post for moderation
      description: 'The body depends on the site you call. The post is charged, queued and

        moderated; poll `GET /v1/posts/{id}` for the result. While the post is

        queued, the response carries `moderation`: `state` is `running` (a

        decision within about a minute) or `starting` (the model starts on

        demand after an idle period; about 20 minutes), with

        `estimated_decision_at` and `retry_after_seconds`. A `Retry-After`

        header says when to poll next.


        Send an `Idempotency-Key` to make retries safe: a repeat of the same

        request returns the first response (with `Idempotent-Replayed: true`)

        and is never charged twice. Add `?dry_run=true` to run every check a

        real post gets — validation, price, account standing and the

        prefilter — without charging or storing anything.'
