get_all_game_data
Retrieve comprehensive in-game data from the League of Legends client for testing and analysis purposes. This tool accesses all available game information through the Live Client Data API.
Instructions
The Live League of Legends Client Data API has a number of endpoints that return a subset of the data returned by the /allgamedata endpoint. This endpoint is great for testing the Live Client Data API, but unless you actually need all the data from this endpoint, use one of the endpoints listed below that return a subset of the response.
