Error in query for Worldwide Governance Indicators data
xxpeng opened this issue · comments
The query for any indicators in the Worldwide Governance Indicators database does not work due to error in the API address as shown below. The source id should be 3, instead of 2.
APIResponseError: APIError: JSON decoding error (https://api.worldbank.org/v2/en/sources/2/series/CC.PER.RNK.LOWER/country/NPL/time/all?per_page=1000&page=1&format=json)
Default database is WDI (db=2). To target a different database:
import wbgapi as wb
wb.data.DataFrame('CC.PER.RNK.LOWER', 'NPL', db=3)
or:
wb.db = 3 # set global option
wb.data.DataFrame('CC.PER.RNK.LOWER', 'NPL')
So the wb.data.DataFrame() could only request data from one database each time? If you have a list of indicators from multiple databases, you would have to parallel loop indicators and databases.
If you want multiple indicators from the same database, you can request them in one call. If they are in separate databases, you need to issue separate requests for each database.
To see why, look at the "lastupdated" column for just the first five available databases; they do not all update at the same time:
>>> wb.source.info()

An indicator like SP.POP.TOTL (population) is included in 13 different World Bank databases. Which one did you intend to request?
