Frequently asked questions

Most data sources are updated every four to twelve hours. Refreshed data exports are published several times a day (currently ca. every six hours). You can see a list of any errors or warnings each dataset has generated.

For data sources that require screen scraping rather than publishing structured data, a HTTP response cache with a maximum age of 14 days is used to avoid running into rate limiting errors.
