Brazil Central Bank Open Data vs Open Government, ACT

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.

Data.act.gov.au is the Australian Capital Territory's open-data portal, run on Socrata; its catalog discovery API at `www.data.act.gov.au/api/catalog/v1` answers keyless GETs with full dataset JSON and a wildcard `Access-Control-Allow-Origin` header (the bare `data.act.gov.au` apex briefly redirects through plain HTTP before landing back on the `www` host over HTTPS, so link to `www` directly). Individual datasets are queryable through Socrata's SODA API in JSON or CSV, covering ACT government services, planning, and community data.
