# Exists **Introduction** The “Exists” step is used to check whether a specific key exists in the cache. This step is useful for determining if data has been previously stored, allowing your automation to make decisions based on the presence or absence of cached data. **Configuration** • **Key**: The unique identifier for the cached value you want to check. This parameter is required to specify which cache entry to verify. • **Group**: (Optional) The group to which the cached entry belongs. **Outputs** • **Exists**: A boolean output that indicates whether the specified key exists in the cache. If the key is found, the output is **Yes**; otherwise, it is **No**. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
