You can use files as sources for any of your corpora. Files can be added via the Web App or via the Create Corpus File Upload API.

​
Upload Files via Web App

1

Create New Source

  • Go to RAG in the Ultravox web application.
  • Click New Source in the top right corner.
2

Add Details and Files

  • Select the Collection to which you want to add the content.
  • (Optionally) Add a Name and Description for the new source.
  • Select Document and add files.
3

Save

  • Click Save and wait a few moments for your content to be uploaded and ingested.

​
Upload Files via API

To upload files using the API, follow these steps:
1

Step 1: Request Upload URL

  • Use the Create Corpus File Upload API
  • Include the MIME type string in the request body
  • This returns the URL to use for upload and the unique ID for the document
  • URLs expire after 5 minutes. Request a new one if it expires before using it
The URL that is returned is tied to the provided MIME type. The same MIME type must be used during upload.
2

Step 2: Upload File

  • Use the presignedUrl from Step 1 to upload the document
  • Ensure the MIME type in the upload matches what was specified in Step 1
For example, if we requested an upload URL for a text file (MIME type text/plain):
FILE_PATH="/path/to/your/file"
UPLOAD_URL="https://storage.googleapis.com/fixie-ultravox-prod/..."

curl -X PUT \
  -H "Content-Type: text/plain" \
  --data-binary @"$FILE_PATH" \
  "$UPLOAD_URL"

Step 3: Create New Source with Uploaded Document

You can provide an array of Document IDs to bulk create a source.
