Really enjoyed this practical breakdown. I’m still learning about AI agents and backend integration, so I appreciate that you didn’t just focus on the “wow” factor you also covered things like timeouts, token costs, failed runs, and thread management. Those are the details that often become important only after you start building something real. The MongoDB example also makes the concept much easier to picture in a real MERN application. I especially liked the point that the API is essentially taking care of a lot of the plumbing rather than magically solving everything. This gives a much more realistic idea of where it can actually be useful. Thanks for sharing such a hands-on perspective!
