Revoke a single session: POST /v1/sessions/{session_id}/revoke with no body. The response returns the Session with status 'revoked'.
To sign a user out everywhere, list their sessions filtered to status=active and revoke each session id returned.
SDK equivalents: clerkClient.sessions.getSessionList({ userId, status }) and clerkClient.sessions.revokeSession(sessionId).

Known gotchas
Revocation takes effect at the next token refresh, not instantly. An already-issued session JWT stays cryptographically valid until it expires (60 second default lifetime), so a revoked user can retain access for up to that window unless you also check session state server-side.
limit is capped below 501 and defaults to 10, so a user with many sessions will silently be truncated if you do not paginate.
The status values are easy to conflate: 'ended' means the user signed out but the session remains on the Client, 'removed' means signed out and removed from the Client, 'revoked' means the application terminated it server-side.
Listing requires user_id or client_id. A bare GET /v1/sessions is not a documented way to enumerate an instance.
Instance rate limits apply: 1000 req/10s production, 100 req/10s development. Revoking every session for a large tenant needs throttling.
