Interacting with Google Colab directly via an API to execute code programmatically is not officially supported. Google Colab is designed as an interactive environment primarily accessed through its web interface. However, you can achieve similar functionality by combining Colab with other Google Cloud services or by using workarounds. Here's how you can approach this:

• Google Colab: Not designed for direct API interaction. Use workarounds like automation or combine it with a custom backend.
• Google Cloud AI Platform Notebooks: Better suited for API-driven interactions and programmatic execution.
• Self-Hosted Jupyter Notebook: Most flexible option for building a custom API-driven solution with GPU support.

If you need a fully API-driven solution, setting up your own Jupyter Notebook or using Google Cloud AI Platform Notebooks is the recommended approach.
