}Browse lobbies
Browses lobbies in the project. Client keys always receive public lobbies
only. include_private is ignored for them, which is what keeps invite
codes meaningful. No x-player-id is required to browse.

}Authorizations
Per-project client key, prefixed ck_live_. Player-facing endpoints
only, and browse never returns private lobbies. Safe to ship in a game
binary: a leak exposes one project's player surface, nothing else.
Headers
Optional player identity. When present the response may include player-specific fields. Trusted verbatim, never verified.
1 - 128"player_1"
Query Parameters
