This Val Town app converts Wikipedia articles into conversational podcast episodes. It:

1. Fetches content from Wikipedia articles
2. Transforms the content into engaging podcast scripts using OpenAI
3. Converts the scripts to audio using Google's Text-to-Speech service

To use this app, you'll need to set up the following environment variables in Val Town:

• OPENAI_API_KEY: Your OpenAI API key
• GOOGLE_APPLICATION_CREDENTIALS: Your Google Cloud credentials JSON (stringified)

1. Make a POST request to the HTTP endpoint with a JSON body containing:

   {
     "article": "Article_Title_Or_URL",
     "voices": ["en-US-Neural2-F", "en-US-Neural2-D"]  // Optional: Specify Google TTS voices
   }

2. The app will return a link to the generated audio file.
