#### **Custom AI Agent Development**

* **Goal**: Combine multiple APIs to handle real-world tasks, such as summarizing news articles and emailing them to a mailing list.
* **Key Functions**:
  * `search_internet` to find news.
  * `send_usdc` (custom) that calls an external transaction API
* **Workflow**: Each morning, the agent grabs fresh headlines, summarizes them, and emails a neatly formatted report—no manual input required. Ideal for a small business or project team wanting automated updates.
