/scene-participants

Retrieves the list of participant wallet addresses connected to a scene or world room.

Query Parameters:

• pointer + realm_name: For scene rooms (pointer is the base parcel, e.g., "-7,-2"). The scene ID is resolved from the catalyst. realm_name defaults to "main".

• realm_name alone: Treated as a world name (e.g., "mycoolworld.dcl.eth")

Response: Returns an array of wallet addresses (lowercase, 42 characters) of users currently connected to the room. Returns an empty array if the room doesn't exist or has no participants.

Query parameters

pointerstringOptional

Scene base parcel (e.g., "-7,-2"). The scene ID is resolved from the catalyst using this pointer. When provided, realm_name defaults to "main" if not specified.

Pattern: ^-?\d{1,3},-?\d{1,3}$

realm_namestringOptional

When used with pointer: identifies the realm for scene rooms (default: "main"). When used alone (without pointer): treated as a world name (must end with .dcl.eth).
