## 🔎래퍼런스

The issue mentions optimizing fetch API integration and possibly using react-query for modularization. First, examine the existing API call patterns in the codebase, likely in services or hooks. Research how react-query or similar libraries handle data fetching and caching. Determine the scope: whether to create a new module or refactor existing calls, and define what 'optimization' means here—caching, error handling, or reducing boilerplate.
