Government — entry 069 of 90
Open Government, Portugal
Dados.gov.pt is Portugal's national open-data portal, self-hosted on the same open-source uData platform as France's data.gouv.fr and Luxembourg's data.public.lu. Its `/api/1/` REST endpoint returns dataset metadata as JSON with no key required. Unlike the other two uData deployments in this cluster, its live API does not grant `Access-Control-Allow-Origin` to arbitrary origins (a `Vary: Origin` header shows it checks the origin but only allows an internal allowlist), so cross-origin browser calls fail without a proxy.
