AI APIs & Structured Outputs

Learn to call a model over a real API: make your first call, stream the reply, get clean JSON out, and handle errors, rate limits, and secrets like a pro — not just in a playground.

Audience: A developer who understands how the model works and wants to wire it into their code and build a stable, production-ready service on it.
