- both V1 and V2 APIs - Rate limiting wrapped into a new method - check_rate_limiting - delegates to the previous daily limit and the new though put limit - Rate limiting done on key type. Each key has it's own limit (number of requests) and interval (time period of requests) - Configured in the config. Not done on a per-env basis though could be in the future.
