Artificial Intelligence Lesson 3 of 4

Building Autonomous Workflow Pipelines with APIs

28:50 AI for Everyday Problem Solving

Connect LLMs to real-world data pipelines using modern API calls, function calling, and structured JSON output.

Lesson notes

Chat interfaces are great for manual questions, but real business value is unlocked when AI runs as a programmatic function inside automated workflows.

What you'll learn

  • Calling AI APIs programmatically using JavaScript or Python
  • Using Function Calling / Tool Calling to interact with external databases and APIs
  • Handling error recovery, retries, and schema validation

1. Function Calling Explained

Modern LLMs can decide when to invoke external tools (such as querying a database, calculating math, or sending an email) and return the structured parameters needed for execution.
