# Business Use Case: Hello World API

A platform team needs to verify that the AI agent pipeline can deliver **runnable, shippable code end-to-end** — not just a script, but a tested REST service with a container image. This is the cheapest possible validation before investing in larger demos.

## Business need

We have no shared baseline for "did the agents finish the job?" New contributors spend too long getting a first working artifact, and we can't compare CrewAI, LangGraph, and Claude Agent SDK on identical specs without a repeatable reference scenario.

## What matters

- Working API with health check and basic item CRUD
- Tests pass; Docker image builds and runs
- Same `input.json` produces comparable artifacts across backends

## Who asked for this

Platform and DevEx engineers validating the pipeline. Engineering managers benchmarking agent frameworks.
