Initiate a multipart upload for large files. This endpoint provides the necessary information to start a multipart upload process.

Supports both single file and bulk upload requests. For bulk uploads, pass an array of upload objects (maximum 100 items). The response format matches the request format - a single object for single file requests, or an array for bulk requests.

Example CURL command (single file):

  curl -X POST https://lilt.com/v2/upload/s3/multipart?key=API_KEY \
  --header "Content-Type: application/json" \
  --data-raw '{
    "filename": "large-file.zip",
    "type": "application/zip",
    "metadata": {
      "size": 104857600
    }
  }'

Example CURL command (bulk upload):

  curl -X POST https://lilt.com/v2/upload/s3/multipart?key=API_KEY \
