Additional anonymous API use limitation
On top of the normal rate limits, requests to active player/leaderboard combinations now fall under an additional, stricter rate limit.
You may only request the same player/game combination 3 times per 60 minutes. When this limit is exceeded, you will receive a “Too Many Attempts (game and player combination)” rate limit error.
We are not accepting API key requests until the launch of the V2 endpoints (see V2 blogpost).
