Examples

Two complete projects ship in the repository. CI checks both with aat validate --strict, and runs the shop's plans against the sandbox.

Example	API	What it shows	Needs
Shop	An offline e-commerce API served by aat-sandbox	Everything: a 17-operation graph, workflows with slots and addons, a Lua transform, layers and batch matrices with dedup, us/eu environments, a separately hosted payments API, negative tests and mutations, retries, checkpoints, a visualizer, MCP configuration, and an integration kit packaged from the project	Nothing — no network, no account
Petstore	The public Swagger Petstore	The smallest working project: four operations, two workflows, two recipes, and graph cleanup pairing	Network access

Examples against real APIs (Duffel flight booking, GitHub, and Stripe) are planned; see the roadmap.

The Airline case study describes the private project AAT was built for — 74 operations and 53 recipes — and which features that scale relies on.

To build a project of your own step by step, follow the Tutorial, which recreates a smaller version of the shop by hand.
