Investigations

Introduction

This use case outlines a three-step investigative workflow utilizing Sayari API endpoints to uncover detailed information about entities.

Conduct an investigation workflow in three steps:

1. Entity Search: Search for entities of interest against the Sayari Knowledge Graph and retrieve an initial profile.
2. Entity: Access the detailed profile of the entity, including relationships and records.
3. Traversal/Ownership: Explore relationships using Traversals and uncover an entity’s ownership connections and holdings.

Step 1: Entity Search

Initiating an investigation starts with identifying and searching for entities of interest within the Sayari Knowledge Graph.

Example Case: Investigating Oleg Deripaska, a Russian billionaire
