# EMBED.DEDUP.GET

> Fetch the stored embedding for a content hash.

URL: https://docs.hotkv.com/commands/embed-dedup-get/

```
EMBED.DEDUP.GET namespace hash
```

- Group: Embeddings
- Complexity: O(1)
- HotKV Cloud: Performance and Scale plans
- On-Premise: requires the embed-dedup license feature

Embedding de-duplication stores each embedding once per content hash and counts references to it, so the same content embedded by many users or documents is stored, and paid for, only once. You compute the content hash and the embedding; HotKV keeps them in named namespaces. `EMBED.DEDUP.GET` returns the embedding stored under `hash`, so
you can skip calling the embedding model. In an existing namespace, each call
counts as a hit or a miss in [EMBED.DEDUP.STATS](https://docs.hotkv.com/commands/embed-dedup-stats/index.md).

## Return value

| Case | RESP2 | RESP3 |
| --- | --- | --- |
| Found | Bulk string: the embedding | Same |
| No such hash or namespace | Nil bulk string | Null |

Errors:

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

## Examples
