LOL Champion and Summoner Stats. To consume a service, perform a GET request on api.elophant.com/v2/<region>/<resource>. Remember, you must include your developer key for authentication (<resource>?key=). Each developer is currently rate-limited to 1,000 calls every 15 minutes. We highly discourage making an unreasonable amount of requests (100 calls/second). All calls now return the proper content-type for Json. Also, the number of requests remaining has been added to the header. This value is updated immediately. The regions we current support include: NA, EUW, EUNE, and BR.
