The list of APIs here provide programatic access to the underlying knowledge sources they cover. They were built using BioThings SDK and follow the same design pattern of our official BioThings APIs (MyGene.info, MyVariant.info, MyChem.info, etc). These APIs are serving as the Knowledge Providers (KPs) in the NCATS Biomedical Data Translator project. They were deployed to the NCATS Cloud infrastructure for production use.
We are continuing expanding the list of KP APIs here as new knowledge sources are identified. You are always welcome to suggest a great resource to us as well.
