Before implementing 4DAIKit features, verifying the API key configuration with a simple connection test helps identify issues early.

Example :

var $result : Object $result := cs.AIKit.OpenAI.new("AI_API_KEY").models.list() If ($result.success)    ALERT("✓ Connected! Models available: " + String($result.models.length)) Else    ALERT("✗ Connection failed. Check your API key.") End if

models.list() is the best lightweight endpoint for testing, as it confirms authentication using minimal tokens.
