Useful for differentiating free and paid tiers. ```python from upstash_ratelimit import Ratelimit, SlidingWindow from upstash_redis import Redis class MultiRL: def __init__(self) -> None: redis = Redis.from_env() self.free = Ratelimit( redis=redis, limiter=SlidingWindow(max_requests=10, window=10), prefix="ratelimit:free", ) self.paid = Ratelimit( redis=redis, limiter=SlidingWindow(max_requests=60, window=10), prefix="ratelimit:paid", ) # Create a new ratelimiter, that allows 10 requests per 10 seconds ratelimit = MultiRL() ratelimit.free.limit("userIP") ratelimit.paid.limit("userIP") ```
