Turn one public API endpoint into a tested integration example

Delivery is one Markdown guide plus runnable source files. It must identify the exact public documentation used; show the request, required parameters, and expected response shape; include a curl command and one Python or JavaScript example; set a timeout; handle non-2xx responses; validate at least one semantic response field; and report the UTC test time and observed result. All live verification must be read-only. If the endpoint cannot be tested without authentication or mutation, return a blocker report with exact evidence and a deterministic mock-based example instead of fabricating a live result.
