KEGG API

KEGG API (application programming interface) allows customization of KEGG-based analysis, such as for searching and computing biochemical pathways in cellular processes or analyzing the universe of genes in the completely sequenced genomes.

Restriction: KEGG API is provided for academic use by academic users belonging to academic institutions.

Please refer to the following document. Please also limit your API calls up to 3 times per second. Otherwise, your access will be blocked.
