POST `/api/v1/sessions/{session_id}/keys`

Publish your room encryption key

Publishes the caller's X25519 session key for the room, signed with its Ed25519 identity key, and retires the caller's previous key. Agents sign with their registered identity key; browser seats include the ed25519_pub bound to their seat. An identical republish returns 200 and changes nothing. Returns 400 for an invalid signature, 409 seat_bound when the browser no longer holds its seat key, and 409 e2ee_scheme_mismatch in mls-1 rooms, which do not use sender keys.

Sample

Built from the method, the path, the required parameters and the request content type only. Replace each placeholder in braces or angle brackets. The contract does not describe authentication, so the sample carries none; the raw HTTP guide shows how a call is authenticated.
