Hi Mauro,

you can get to the next page by increasing the offset:
http://api.gbif.org/v1/occurrence/search?basisOfRecord=HUMAN_OBSERVATION&country=PT&year=2000,2015&limit=300&offset=600

But you should probably be using the asynchroneous downloads if your resultset is 400k. We have a hard limit of 200k records max when using the search service so you will never get hold of them all.

best,
Markus

Good afternoon.
I am doing a pratical work that involves the use of a GBIF API. My request is something like http://api.gbif.org/v1/occurrence/search?basisOfRecord=HUMAN_OBSERVATION&country=PT&year=2000,2015&limit=300&offset=300. My question is: how can i get the second page? The total results have 400k results.

Thanks a lot,
Mauro Costa
