Monitor API rate limits, cache hit rates, and request throughput in real time. Data refreshes every 10 seconds.
Outgoing Vercel API requests are gated through a token-bucket rate limiter. Tokens refill at 5/sec with a burst capacity of 20.
DynamoDB-backed stale-while-revalidate caching. Stale data is served immediately while a background revalidation fires.
Concurrent identical requests are collapsed into a single API call. All callers share the same in-flight promise.
