      description: 'Business+ tier SSE endpoint that filters the broadcast stream to

        line-MOVES only. Customer configures a threshold (in American-odds

        cents) and we push an event the moment a tracked side crosses it.


        Each event has shape:

        data: {"type":"odds_drop","event_id":"...","bookmaker":"...",

        "side":"h2h_home","prev":-110,"new":-120,"delta":-10,

        "direction":"toward_favorite","timestamp":1747...}\n\n


        Single-sport subscription:

        GET /v1/odds-drop/baseball_mlb?apiKey=...


        Multi-sport subscription (one connection, many sport_keys):

        GET /v1/odds-drop/all?apiKey=...

        GET /v1/odds-drop/multi?apiKey=...&sports=baseball_mlb,basketball_nba


        The wildcard ''all'' value subscribes to every sport_key with broadcast

        activity in the last 5 minutes (~100-200 sport keys at peak). Drops

        include a `sport_key` field so you can route them downstream.'
