Hi Mani K. we didn’t use an API as such, it is a bespoke SaaS product we have built, for building and maintaining , and integrating knowledge graphs easily without needing to build your own data back-plane. See https://datagraphs.com Data Graphs comes with its own set of APIs to search, query, navigate, and integrate the data stored. The demo above is a read-only demo view of the product pre-loaded with various open datasets from kaggle.
