So there is no possibility to make unlimited paginated browser with api.elrond.com?

Yes and no, yes it's possible because you can fetch older transactions. No it's not possible because you will have to paginate one by one and have no way to jump to an older page. I will describe the process. First you fetch the first 50 entries: size=50&order=desc After you received them and want to see the transactions before them you would take the timestamp from the last transaction you received and use that for the 2nd page: size=50&order=desc&before= Same for the third page, you take the new last transaction and use that for the query: size=50&order=desc&before=
