Dear Allin,
The main public providers of economic data here is Brazil are the
Banco Central do Brasil (BCB) and IBGE. Take a look at the Wikipedia
entry:
"The Brazilian Institute of Geography and Statistics or IBGE is the
agency responsible for official collection of statistical, geographic,
cartographic, geodetic and environmental information in Brazil."
They both have API's for retrieve data and I know how to use them
(actually I wrote some scripts that we use at Ministry of Finance). I
was thinking to send an email to DB.NOMICS offering that solution but
I had a better idea: IMHO, it would be great, in terms of Gretl's
visibility, that this kind of help could be done by the Gretl Team
itself.
Additionally we could try to be listed at Resources section of the
DB.NOMICS website (today it has R and Python listed).
Best,
Henrique Andrade
