Tools & requirements

Python and a separately installed FastAPI environment; example requirements pin FastAPI 0.142.2/Pydantic 2.13.5/Starlette 1.7.0/AnyIO 4.15.1/HTTPX2 2.13.1. Windows evidence used Python 3.12.4. Original skill describes additional features outside the fixture scope.

Free MIT instructions and references. The experiment uses synthetic in-process API requests, no external service, credential, cloud account or paid model. Dependency installation contacts the public registry separately. Do not deploy intentional response counterexamples; this is not authentication or a security certification.
