Get an entire time-series dataset

Our time-series API provides users the functionality to download an entire time-series dataset in a single call.

This method has two restrictions:

  • This method is not available for free datasets, only premium data products.
  • This method is only available for subscribers of the premium data product they wish to download.

Irrespective of whether you call this method through the API, R or Python, the output format is always the same: a single zipped CSV file of the entire database. The first column of this CSV is the time-series code; the remaining columns replicate the columns of individual datasets.

...

In addition to functionality to download the entire dataset, the Time-series API also provides functionality to download a partial file, which includes only the latest available observation for each time-series in the dataset.

This functionality has the same restrictions as outlined above in that it only works for premium data products.
