Thanks — you're asking how to (1) check if a LiveKit room with ID X exists, and (2) check if there's a recording for it. Here are the practical ways to do both. 1) Check if a room exists • Use the Server SDK ListRooms API to list active rooms and look for the room SID (or name). ListRooms only returns currently active rooms, so a room that has already ended will not appear. • Example flow: a. Call ListRooms. b. Search the returned rooms for

room.Sid == "X"

(or match by name if you only have the name). c. If found → the room is active; if not found → the room is not currently active. 2) Check if a recording exists for that room • Use the ListEgress API to list egress (recording/stream) sessions and filter by the room SID or room name. • Check egress items where

egress.RoomSid == "X"

(or matching name) and

egress.Status

is

EGRESS_ENDED

(or

EGRESS_ENDING

depending on timing). The

Output

field contains the recording location (e.g., S3 path) when the egress has finished. • Alternatively, subscribe to the

egress_ended

webhook to be notified when a recording completes; the webhook includes

egress_info

with recording details. If you want, tell me: • Which Server SDK/language you’re using (Go, Node, Ruby, Python), and • Whether you have the room SID or only the room name. I can then provide a concise code snippet for your SDK or exact request payloads.
