This little API can fetch data from the ECB statistical data warehouse. It will fetch 1 data column at a time, and return a time-series as a pd.DataFrame (with date-time as an index). Small checks are performed.
The only input is the series name, corresponding to the 'Series Key' of the table that one wants to fetch. This key is indicated on each data series found in the data bank.
