`404`	Account not found	`connectedAccountId` not found or belongs to another user
`409`	Post already scheduled	Duplicate post for the same account + platform + time

`429`	Rate limit exceeded	30 requests/minute per user

Safety Gates

The scheduling endpoint runs every post through a safety gateway before queuing:

Duplicate content — blocks identical text posted to the same account within the last 24 hours
Daily post limit — enforces a per-account maximum posts per day (platform-dependent)
Minimum gap — enforces a minimum time gap between consecutive posts on the same account
Account health — blocks scheduling if the account's token is expired or invalid

When a safety gate blocks a post, the response includes a reason field:

{
  "error": "Post blocked by safety rules",
  "reason": "duplicate_content"
}

Duplicate schedule requests for the same connectedAccountId + platform + scheduledAt combination are automatically detected and return 409 Conflict instead of creating a duplicate post. This protects against double-scheduling from retried requests.
