# SCACHE.LIST

> List the names of all semantic cache namespaces.

URL: https://docs.hotkv.com/commands/scache-list/

```
SCACHE.LIST
```

- Group: Semantic cache
- Complexity: O(N) where N is the number of namespaces
- HotKV Cloud: Performance and Scale plans
- On-Premise: requires the semantic-cache license feature

The semantic cache returns a cached LLM response when a new query embedding is similar enough to one you stored, so paraphrased requests can hit. Your application computes the embeddings. `SCACHE.LIST` returns the names of all namespaces on the server you
are connected to, in no particular order. In a cluster, each node lists only
the namespaces it holds.

## Return value

| Case | RESP2 | RESP3 |
| --- | --- | --- |
| Always | Array of bulk strings (empty if there are none) | Same |

Errors:

- `ERR wrong number of arguments for 'scache.list' command` if the argument count is wrong.
- `NOLICENSE semantic-cache requires a HotKV license. Contact sales@hotkv.com` if your license does not include the `semantic-cache` feature.

## Examples
