📋 Listed tier — endpoint check pending

This API comes from the open public-apis dataset (MIT license), and its official site passed our link check on 23 Oct 2026 (HTTP 200). We have not yet run a full endpoint test on it — those happen in weekly passes, most-wanted first. Until then: no playground and no fake badges, just an honest listing.
