City, Prague Open Data
Prague's open-data platform is Golemio, run by Operátor ICT; the stored `opendata.praha.eu` link now redirects to a bare metadata catalogue page rather than a working API, so `url` is corrected to Golemio's own homepage. A live GET against `api.golemio.cz/v2/gtfs/stops` returned `401 Unauthorized` with a wildcard `Access-Control-Allow-Origin` header, confirming the API requires a free registered API key (correcting the stored `auth: None`) and serves exclusively over HTTPS (correcting the stored `http://` link).
