## Overview

This repository is a third-party catalog of Refinitiv Eikon’s public API surface, not an implementation or executable product. Its principal user journey is to choose an API capability, consult its specification and authentication guidance, then call the corresponding Refinitiv service to retrieve financial data. The graph preserves documented API domains and the named workflow examples. Source excerpts were unavailable, so links between individual workflow documents and API operations are omitted where their wiring cannot be verified.
