-- See Global Unlock Sample for sample code.

local http = chilkat.Http.new()

-- Implements the following CURL command:

-- curl https://api.openai.com/v1/audio/transcriptions \
--   -H "Authorization: Bearer $OPENAI_API_KEY" \
--   -H "Content-Type: multipart/form-data" \
--   -F file="@/path/to/file/audio.mp3" \
--   -F model="whisper-1"
