A practical guide to preventing repeated API calls in Android using OkHttp interceptors with endpoint-level cooldowns. The approach generates request fingerprints from HTTP method and URL path, blocks duplicate in-flight requests, and throttles repeated calls to the same endpoint using configurable cooldown durations stored in a StateFlow. The implementation uses coroutine-based cleanup instead of timestamp expiration to avoid memory leaks from stale fingerprints. Cooldowns can be updated at runtime via remote config or feature flags without rebuilding the networking layer.
