# Get one knowledge collection by id

> Retrieve one collection, including the embedding model it was created with. An id that is unknown, one in another organisation and a malformed id all give 404.

Returns `404` both for an ID that does not exist and for a collection that belongs to another organization. A malformed ID also returns `404`.

Any role in the organization can read a collection.
