Could you build this?

Partial Building client SDK wrappers and basic dashboards is straightforward, but building ultra-low-latency, distributed, highly available rate limiting and high-throughput event metering infra requires systems engineering.

What it would actually take: The system requires an edge reverse-proxy / SDK middleware that syncs counters to a distributed, low-latency in-memory datastore (e.g., Redis cluster using sliding window or token bucket algorithms) coupled with an asynchronous event-streaming pipeline (Kafka/ClickHouse) for analytics. It demands distributed systems engineering to handle high-throughput traffic without adding latency overhead or dropping usage records.
