}List a session’s turns
Returns the conversation, oldest first: one row per turn, carrying the prompt or the answer, the run status, and what the run cost.
Cursor-paginated — send pagination.nextCursor back as ?cursor= until hasMore is false. Pages default to 20 turns because a turn carries a whole answer.
An answer longer than 256KB is returned truncated, with content_truncated true and content_length giving its real size; read the turn’s job to get it in full.
An assistant turn that stopped reporting is reconciled to STALE while the history is read, so a session stuck behind a dead run is freed by reading it.

}Authorizations
API key for authentication
Headers
Accepted for client uniformity but IGNORED on this endpoint. It has no side effects, and a retry can legitimately return different results, so replaying a cached response would hand back stale data. Every request executes fresh: no 24h window, no replay, no Idempotent-Replayed header, and no key-reuse 422.
Path Parameters
Session to read turns from.
Query Parameters
Turns per page (default 20, max 50). Lower than other list routes because a turn carries a whole answer.
1 <= x <= 50Opaque cursor from a previous response’s pagination.nextCursor. Omit it for the first page.
