Using the spectator-v4 API

The spectator-v4 API is perfect to gather data about a live match in League of Legends. Be aware that the live data does not include CS, KDA or similar stuff from the current ongoing game.

The participantDTO has several intersting fields as well. Unfortunaly, stats like role, KDA or CS aren't included in the participantDTO.

There are two endpoints for the spectator-v4 API. One gets you the live-status of a requested summoner, the other endpoint is recommending you live-games to e.g. display on your site.

The base-url for the spectator-v4 API is the following: https://{platform} Please keep in mind to replace {platform} with your current platform.


This endpoint gets your information about a specific summoner and their ingame status. The API returns a 404 - Not found status if the summoner is not ingame, don't get confused by that. https://{platform}{encryptedSummonerId}

To execute this request, you need an encrypted summoner id using summoner-v4, so you might want to know how to get this first: Using the summoner-v4 API. The response is exactly as shown above (response heading).

The featured-games endpoints returns (usually) several live games. The response is a list of the response shown above (response heading): List[CurrentGameInfoDTO].

   "gameList": [
   "clientRefreshInterval": 300

The additional fields are the following:

Field Type Note
gameList List[CurrentGameInfoDTO] Contains several featured live games.
clientRefreshInterval Number The suggested interval to wait before requesting FeaturedGames again.

Using this path you can request the featured games.


It is recommend to not call this page more often than recommend in "clientRefreshInterval", as the response isn't changing fast anyways and you can save up some API calls.
