* 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

* 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.
