Thanks for that! I'm using Perl with json module and cURL to get the data. So up until now I haven't been looking at the headers at all.   CURL -i  will show the headers and it does indeed have the link with the last tag. So I'll add that to the bag of tricks for any other pages that have the 1000 limit.  I've only come across it on the org/devices so far and I did notice that the last serial in the returned json array was the "marker" and if I asked for after that I got the next 1000.   Looking at the headers is something I didn't think of.   Cheers! ...
