Usage

1. Set up your virtual environment

   Mac

   uv venv --python 3.12
   source .venv/bin/activate
   

   uv venv --python 3.12
   .venv\Scripts\activate
   
2. Set your API key

   export OPENAI_API_KEY=xxx
   export ELEVEN_LABS_API_KEY=xxx
   export FIRECRAWL_API_KEY=xxx
   
3. Install dependencies

   uv pip install -U openai elevenlabs firecrawl-py agno
   
4. Run Agent

   This script scrapes the URL with Firecrawl and generates audio with ElevenLabs on every run. Both are metered APIs and may incur provider charges beyond their free tiers.
