*  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/chat/completions \
*    -H "Content-Type: application/json" \
*    -H "Authorization: Bearer $OPENAI_API_KEY" \
*    -d '{
*       "model": "gpt-3.5-turbo",
*       "messages": [{"role": "user", "content": "Say this is a test!"}],
*       "temperature": 0.7
*     }'

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

*  Use this online tool to generate code from sample JSON:
*  Generate Code to Create JSON

*  The following JSON is sent in the request body.

*  {
*    "model": "gpt-3.5-turbo",
*    "messages": [
*      {
*        "role": "user",
*        "content": "Say this is a test!"
*      }
*    ],
*    "temperature": 0.7
*  }

loJson = CreateObject('Chilkat.JsonObject')

loJson.UpdateString("messages[0].role","user")
loJson.UpdateString("messages[0].content","Say this is a test!")
loJson.UpdateNumber("temperature","0.7")

*  Adds the "Authorization: Bearer $OPENAI_API_KEY" header.
*  This is NOT a real key.  Change the "sk-vi...." to your own key.
