List the recurring posts (series) in the workspace (the current one unless workspaceId names another), created by passing recurrence to create_post. Returns { recurringPosts, total, hasMore }; each series has id, status (ACTIVE, PAUSED or ENDED), pauseReason when paused, frequency, interval, weekdays, startsAt, timezone, endsOn or maxOccurrences, nextOccurrenceAt, occurrenceCount, and the content and platforms every occurrence copies. Only the next occurrence of an ACTIVE series exists as a SCHEDULED post, created about 24 hours ahead; list_posts shows it with recurringPostId set. A series pauses itself after 3 failed posts in a row, when the subscription lapses, when its creator loses workspace access, when one of its accounts is disconnected, or when a platform rejects the content; pauseReason and lastError say which. limit is 1 to 100 (default 20); page with offset while hasMore is true. Editing a series or skipping one date is only possible in the AdaptlyPost app.
