I was reading the KEGG plea and I found that it doesn't forbid to useusing the KEGG API. Then, what is in the FTP server the license for personal use/academic use that it is not covered by the API?
Or I could download all the database via the API?
PDPS: I couldn't find how to download which genes are in which patwhayspathways but it might be I didn't expend enough time with the queries.
