About KEGG API Subscription

Kanehisa Laboratories is now offering a new service called KEGG API Subscription. The purpose of this new service is to promote wider usage of KEGG in real-world applications. In contrast to the existing KEGG API service, which is limited to academic users, this new service is intended for commercial users developing and maintaining products, such as application programs and data analysis services. The new KEGG API service contains all the operations that are available in the academic service, plus additional operations of data uploading and KEGG Mapper analyses. See more details in the following documents.
