Brazil Central Bank Open Data vs City, Gdańsk
A CKAN-based open-data catalogue from Banco Central do Brasil covering 4,200+ datasets — exchange rates, interest rates, public debt, and other monetary time series. Dataset metadata is browsable via the standard CKAN Action API, and most series resolve to the Central Bank's SGS (Sistema Gerenciador de Séries Temporais) endpoints, which return JSON or CSV for a specified date range with no key required.
Otwarty Gdańsk (Open Gdańsk) runs a standard CKAN 2.x installation; a live keyless GET against `ckan.multimediagdansk.pl/api/3/action/package_search` returned full JSON dataset metadata with a wildcard `Access-Control-Allow-Origin` header on both the plain response and an OPTIONS preflight. The catalogue covers Gdańsk municipal transit, budget, and environmental datasets, with individual resources downloadable as CSV, JSON, or XLSX depending on the publisher.
