* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loHttp = CreateObject('Chilkat.Http')

* 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"

* Use the following online tool to generate HTTP code from a CURL command
* Convert a cURL Command to HTTP Source Code
