Schedule X Post

Composes a post and schedules it to send at a future date/time, instead of posting immediately.

Input

text required

The post's text. X caps this at 280 characters for a standard (non-subscriber) account.

sendAt required

When to send the post, as an ISO-8601 datetime (e.g. "2026-09-15T14:30:00"). X's composer only offers minute precision and reads/writes it in the account's own display timezone, not UTC — pass a naive local time (no offset) matching that timezone. X also refuses times inside the next ~10 minutes and more than ~18 months out.
