        "description": "**Availability: pending.** This endpoint is specified ahead of implementation and is not yet live on the hosted API; it ships through recoupable/app#2241. Do not rely on it until this notice is removed.\n\nPublish a video with its copy to **one** connected social account, now or at a set time. Send one request per target account; to post the same video to several platforms, call this once per platform.\n\nWithout `publish_at` the post starts publishing immediately and is returned as `publishing`. With `publish_at` it is returned as `scheduled` and publishes at that time. Either way this returns **202** right away: poll [Get Post](/docs/api-reference/publishing/get) until `status` is `posted`, `failed` or `cancelled`.\n\nThe platform must already be connected for the account (see [Authorize Connector](/docs/api-reference/connectors/authorize)). Copy uses one shape for every platform. Which fields each platform uses, and their limits:\n\n| Platform | `title` | `description` | `cover_url` | `privacy`, `tags` |\n|---|---|---|---|---|\n| `youtube` | **required**, video title, max 100 characters | video description, max 5,000 characters | not used (YouTube picks the frame) | used |\n| `instagram` | not used | **required**, Reel caption, max 2,200 characters | Reel cover image | not used |\n| `x` | not used | **required**, post text, max 280 weighted characters (URLs count as 23) | not used | not used |\n| `linkedin` | video title shown on the post | **required**, post commentary, max 3,000 characters | video thumbnail | not used |\n\nLimits are checked here, so an over-length body fails with 400 instead of at publish time.",
