KEGG FTP vs KEGG API I was reading the KEGG plea and I found that it doesn't forbid using the KEGG API. Then, what is in the FTP server license for personal use/academic use that it is not covered by the API?

Or I could download all the database via the API?

PS: I couldn't find how to download which genes are in which pathways but it might be I didn't expend enough time with the queries.
I found the way to download the genes and pathways thanks to this answer using KEGGREST. 

It seems that the API allows to fully download the database because it allows to download info, list, find, get, conv, link, ddi.

In fact in the message of 2011-05-21 it mentions that the API includes more options to download the KGML files that previously where only possible to get via the FTP site.
