Update the specified parameters of a specific document in the user's library.

This is the endpoint for the [Jamba Instruct model](https://docs.ai21.com/docs/jamba-models). This is a foundation model that supports both single-turn (question answering, text completion) and multi-turn (chat style) interactions. You can optionally stream results if you want to get the response as each token is generated, rather than waiting for the entire response.

Delete the specified file from the library. **Restrictions**: Files in `PROCESSING` status cannot be deleted. Attempts to delete such files will result in a 422 error.

Get metadata about a specific file by file ID. The file ID is generated by AI21 when you upload the file.

Retrieve a list of documents in the user's library. Optionally specify a filter to find only files with matching labels or paths. This method returns only metadata about files; to download a file, call `GET .../files/{file_id}/download` When specifying qualifiers with your request, only files that match _all_ qualifiers will be returns. So, for example, if you specify `label='financial'` and `status='UPLOADED'`, only files with the label "financial" AND status UPLOADED will be returned.
