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

loAi = CreateObject('Chilkat.Ai')

* The provider can be "openai", "google", "claude", "deepseek", "xai", or "perplexity".
* Support for additional providers will be added in future versions of Chilkat.
loAi.Provider = "claude"

* Use your provider's API key.
loAi.ApiKey = "MY_API_KEY"

* Choose a model.
loAi.Model = "claude-opus-4-1-20250805"

* Create a new conversation to be maintained locally in memory.
* If the conversation is the first to be created, it is also automatically selected.
lcSystemMsg = "You are a helpful assistant"
lcDeveloperMsg = "Respond only with markdown"
lcConversationName = "test_conversation"
loAi.NewConvo(lcConversationName,lcSystemMsg,lcDeveloperMsg)

* -------------------------------------------------------------------------------------------
* Make the first request...
* Add a text input.
loAi.InputAddText("Say Hello")

* Ask the AI for text output.
lnSuccess = loAi.Ask("text")
IF (lnSuccess = 0) THEN
    ? loAi.LastErrorText
    RELEASE loAi
    CANCEL
ENDIF

* Get the text response.
loSbResponse = CreateObject('Chilkat.StringBuilder')
loAi.GetOutputTextSb(loSbResponse)
? loSbResponse.GetAsString()
? "----"

* -------------------------------------------------------------
* The response is in markdown format.
* Also see Markdown to HTML Conversion Examples.
* -------------------------------------------------------------

* Sample output:

* # Hello! 👋
* ## Welcome!
* It's **great** to meet you. How can I *assist* you today?
* ---
* Feel free to ask me anything, and I'll respond in `markdown` format.

* -------------------------------------------------------------------------------------------
* Send the 2nd request in the conversation.
loAi.InputAddText("Thanks for saying Hello. Please give me a 2 sentence bit of wisdom from Confucious.")
lnSuccess = loAi.Ask("text")
IF (lnSuccess = 0) THEN
    ? loAi.LastErrorText
    RELEASE loAi
    RELEASE loSbResponse
    CANCEL
ENDIF

* Get the text response.
loSbResponse.Clear()
loAi.GetOutputTextSb(loSbResponse)
? loSbResponse.GetAsString()

* Sample output:

* ## Wisdom from Confucius
* > *"The man who moves a mountain begins by carrying away small stones. It does not matter how slowly you go as long as you do not stop."*
* These words remind us that **persistence** and **patience** are the keys to achieving even the most daunting goals. 🏔️
