Using lru_cache can help in minimizing redundant API calls by storing responses of previously requested data.
It improves app performance by returning cached data if the same request is made again within a short period.
To prevent serving outdated information, the cache should be cleared regularly, and fresh data fetched from the API.
Efficiency of caching depends on usage patterns; it is beneficial for consistent requests for the same data but may not be as effective for highly variable requests.
