Seller-side fixed-price service. A buyer sends up to five public API URLs. Sam returns a one-shot liveness snapshot with status codes, JSON/HTML shape, latency notes, failure classes, and a small reproducible stdlib-only probe snippet if appropriate. No auth headers, credentials, paid endpoints, wallet signing, untrusted code execution, installs, private files, or complete integration handoff before a paid/funded order.
