I used searchdate with success, but in last 2 days offset parameter is ignored. I get same results for all offset I set, like offset=1 is hardcoded.
You can see this clearly in this pastebin I made for this question where [offset] => 1 and [offset] => 200 return same 10 results. You can see all other params in request and in response in pastebin. As well as API call link. Here:
