Set zip=true to receive results as a ZIP file. For example, the following command will download a ZIP file containing "sample1.json":

curl -F zip=true \
     -F file=@sample1.wav \
     http://vblaze_name:17171/transcribe \
     -o results.zip

Note that the -o results.zip curl specification is required to save the ZIP data stream to a file. If you omit this specification, the ZIP binary data will be printed to the console.

Since the -o switch is an argument to curl and not to V‑Blaze it may be specified after the file parameters.
