Thanks mmd, As said, I'd like to fetch the latest available augmented diff and keep uptodate. So, to understand it correctly: Every minute I first call the http://overpass-api.de/api/augmented_diff_status which returns an id, e.g. 2111988, then I fetch the augmented diff file http://overpass-api.de/api/augmented_diff?id=2111988 Just want to be sure that this is the correct way to use the API.
