Over this series we built a Scripted REST API by hand — six resources, one at a time. In this final video we build the same API again from a single plain-language prompt, using Build Agent and the ServiceNow Fluent SDK. *You'll learn:* - What Build Agent is and how it scaffolds an application from a single prompt - Why a precise prompt — exact paths, fields, and per-method behaviour — is what makes the output correct - How to verify the generated API against the one we built by hand *Chapters:* - 0:00 Introduction - 1:08 What does Build Agent do? - 1:44 The prompt - 2:38 The ServiceNow SDK - 3:20 Demo - 5:12 Outro *GitHub:* https://github.com/jnichols-servicenow/SN2026-Vehicles-API *Build Agent prompt:* the full prompt used in this video is in the GitHub repo. https://github.com/jnichols-servicenow/SN2026-Vehicles-API/blob/main/vehicles\_api\_build\_agent\_prompt.md *Links:* - ServiceNow Fluent SDK — https://servicenow.github.io/sdk/ - ServiceNow SDK RestApi reference — https://servicenow.github.io/sdk/api/restapi-api - Build Agent — https://www.servicenow.com/docs/r/application-development/build-agent.html *Note:* Build Agent is a new and evolving capability.
